One more PQ up. Overhead equipment design+build and power supply systems in here (http://www.chennaimetrorail.gov.in/PQ%20for%20PSS%20and%20OHE.pdf).

dont we hve to worry abt the Seismic activity in chennai....I beleive recently our zone level was raised. The technology involved may be capable of withstanding..but after all the "cutting" our politicians/officials take, will the project be implemented to its fullest quality. We haven't mastered (?) to lay proper road surface ( except in Gopalapuram, Poes,Greenways...) even in 2010...Hope they don't end up compromising on the quality. Thinking of recent mishaps in Delhi metros haunts me. rescue activities on ground level and underground level are totally different animals I guess.
I pray to almighty that such a event doesn't happen.

Don't worry. if there is a major mishap especially to metro it will cause major doubts about other infra projects in India, then getting money for other infra projects will become very very difficult, although there will be some money given/taken, i guess the quality of work will be better[something like current GQ, it is 100 times better than any other roads laid so far in our country].

remember we have taken a loan for this [not from world bank], if there is a major failure, we cannot repay the loan.then your credibility to get the new/additional loan in future further goes down.

so the mishaps in this case will be very minimal.

Your fear is unfounded. There are umpteen number of underground metro all over the world. Our own Calcutta has underground metro for more than 20 years without any major mishaps.

agreed. cities all over world has roads/bridges...and chennai also has roads..but do they qualify for the word "road". Did you try the new pallikaranai fly over.. if you are a bit faster and not holding strongly to the vehicle... you might end up on he road..such is the surface..totally uneven. my worry was that they should not compromise on the quality of the construction of the tunnels.

The issue with Pallikaranai flyover is not mostly with the flyover itself (agreed, road is a bit bumpy, but it is very wide). The road after the flyover is funny...a six lane flyover that leads to a two lane tarred cart track!

Having said that, seismically, there are more active regions with underground metros - Japan, US west coast, etc. and they seem to be okay...

Looks like Titagarh Wagons & Stadler in fray for Chennai Metro project.

Soma is currently doing an Concrete Pile load testing in which huge blocks of concrete are placed over the piling pillar. The pillar should bear the load. They mark the pillar level before and after placing the blocks . This helps them to ascertain the load bearing capacity of the pillars and soil below. This was done for Koyembedu Flyover there there was an issue of loose soil below the surface

I do not know how much time it normally takes for performing a load test. But we have been hearing only of this test for quite a few months. The photos of the huge concrete blocks piled one above the other were first put up in the forum around Nov 10th.

I know we should not be impatient and expect results overnight. But looking at the frenetic pace of activity in the Legislative assembly photos, the photos of lone cranes in the Metro sites are not very encouraging. I hope it is the normal time frame and not a huge delay.

Stadler Coaches are just awesome.It will be really great if some company can scucessfully receive the technology for making such coaches. I hope and wish our Dream of aerodynamically and aesthetically designed highspeed coaches becomes true sometime in the near future.By the way anyone has go a render of the roling stock for chennai metro? Am curious....:)Thanks

Check their coaches in Hungary at this link (http://infovilag.hu/data/images/2007-12/flirt_stadler_mav.jpg)

Looks gigantic than DMRC coaches. Is it for intercity trains or for metro?

Its certainly taking longer than the usual duration. A load test should not take more than a week. If the results are satisfactory, the works should continue without any further problem.

I believe the issue here is CMRL has not awarded any other contract yet. So, Soma probably is just using the space to park their machinery. CMRL also might not be chasing them for progress until other adjacent contracts are awarded.

There are much than piling concrete blocks. First unless Assembly building which is constructed in Govt land this is built in the middle of an busy road. Try crossing the road once in the 100 ft road when the signal lights are green. Highways dept could not take up road repair in 100 ft road as more than 1 lakh vehicles pass through the road day and night. imagine moving a 250 ton crane in the middle of the road without blocking the traffic. Since the piller is near the cooum river the soil might be loose below the surface and proper care has to be taken while laying the foundation.:ohno:Dont want a delhi incident to be repeated.

With contracts awarded, Metro Rail is on track (http://timesofindia.indiatimes.com/city/chennai/With-contracts-awarded-Metro-Rail-is-on-track/articleshow/5511118.cms)

CHENNAI: Larsen and Toubro (L&T) has won the contract to construct 9.73km of an elevated corridor for the Chennai Metro Rail project that promises to make commuting in the city faster and hassle-free.

Except for the stretch from the Officer Training Academy to Airport, which the Airports Authority of India wants constructed underground, builders have now been identified for almost the entire elevated stretch.

L&T will design and construct the 4.56-km elevated viaduct from Ashok Nagar to St Thomas Mount at an estimated Rs 141.13 crore and the 5.17-km stretch from Saidapet to the OTA at Rs 173.30 crore. The company was awarded the two contracts on Monday, said Chennai Metro Rail chief public relations officer S Krishnamurthy.

A senior official said discussions were on with the AAI on building an elevated corridor between the OTA and the airport as the AAI had requested that this corridor be built underground to prevent it from coming in the way of flight operations on the secondary runway.

“The stretch will be an elevated corridor but the tender process will start only after discussions with airport officials,” he added.

:banana:

^^ So, only that airport stretch and the underground tenders are pending in the major area. :cheers:

I know how difficult it is to work on the middle of the road. But, that is why the contractor is allowed to hoard up the work site, where the work can go on uninterrupted.

Secondly, I believe CMRL or their consultants would have carried out a soil investigation before the award of contract. So, the contractor would be more or less aware of what is beneath the ground. If the soil is not suitable, they should have commenced soil improvement works.

This contract was awarded on 13 Feb 2009, almost one year ago. If someone is seriously working on this project, there would be lots of progress made during this period. But, it is not so. Thats why I assume that CMRL is not really interested in the progress at this stage of the project. I could not understand the logic behind not awarding any other tender after awarding the first contract one year ago.

By the way, I too don't want any mishaps or accidents. In fact, I had seen much worse Metro collapse in Singapore which killed four people and the entire station had to be abandoned and relocated to a new location (The Nicoll Highway Accident in 2004).

Same News in Hindu...

Metro Rail: contracts for viaducts construction awarded

R. Srikanth

Elevated viaducts to be constructed from Saidapet to OTA

CHENNAI: The awarding of contracts for design and construction of elevated viaducts for the two corridors of the Chennai Metro Rail Project is nearly completed.

According to a senior official of Chennai Metro Rail official, except for a small portion of the stretch from St. Thomas Mount to Chennai Airport, contracts for construction of elevated viaducts have been awarded. The design and construction of elevated viaduct does not include stations.

The official told The Hindu on Thursday that two contracts have been awarded to Larsen & Toubro to design and construct the elevated viaducts from Saidapet to Officers Training Academy (OTA) at a cost of Rs.173.30 crore for a distance of 5.17 km and from Ashok Nagar to St. Thomas Mount at a cost of Rs.141.13 crore for 4.56 km. The company has been given two years to complete the work, which is expected to commence soon, the official said.

Earlier, the Hyderabad-based Soma Enterprise had been signed up for construction of the elevated viaduct for a stretch of 4.5 kilometres from Koyambedu to Ashok Nagar for Rs. 199 crore.

The company has presently taken up piling work.

The first corridor of the Metro Rail would be 23.1 km long of which 14.3 km would be underground and connect Washermenpet with Airport via Anna Salai.

The second corridor linking Chennai Central with St. Thomas Mount would be routed through Poonamallee High Road, Anna Nagar and 100-feet Inner Ring Road. The second corridor is 22-km long with the corridor from Chennai Central to Anna Nagar 2nd Avenue being underground for a length of 9.7 km.

:cheers:Thats good news finally. CMRL has decided to award the contracts after one year of the first contract award. The next question is how long will it take to award the tender for the stations.

good news at last !!! I hope the construction works pick up speed. Nothing like seeing action on ground. Any updates on the changeover at St Thomas Mount - wherein MRTS, Suburban and Metro are expected to join? I wish that they also build a bus terminus there providing feeder services to all the adjoining localities.

It is indicated that the company would be given two years to complete.. So 2011 no more seems to be the deadline for completing the elevated portions as promised initially.. :ohno:

anyone associated to MRTS should automatically be blacklisted!

Finally some green light:banana::banana::banana: in chennai metro. CMRL should keep the momentum going. I am keeping my fingers crossed ^^^^^^
Let us hope we get our metro very soon

FOR FASTER TRANSPORT

Builders identified for almost all of the elevated corridor
From Officers Training Academy to the airport, Airports Authority of India wants an underground corridor to be constructed
This will not come in the way of operations on the secondary runway, says AAI
Separate tenders to identify builders to construct stations along the elevated stretch and also at St Thomas Mount Metro rail to have two corridors

Chennai: The Metro Rail plans to issue separate tenders to identify builders to construct stations along the elevated stretch and also at St Thomas Mount which will be a hub of Metro Rail, MRTS and suburban railway line.
“Metro Rail will occupy level two while MRTS will occupy level one of the elevated station that will be built at St Thomas Mount,” sources said.
A pre-qualification bid meeting was held at the Metro Rail office on Thursday to brief companies about the requirements to bid. Work on Metro rail began on June 10, 2009.
Metro rail will have two corridors with a combined length of 45 km — one from Washermanpet to the airport and the other from Central to St Thomas Mount via Koyambedu. The total cost is estimated at Rs 14,600 crore. TNN

^^

This looks if elevated metro part of St.Thomas mt to Koyamedu (approx 10KM) is completed by 2014, we can take MRTS+Metro combination to CMBT from Adyar, T.vanmiyur, Velacherry etc.,. And traffic on IRR can slightly reduce.

But we have to see how MRTS and Metro coordinate on St.Thomas mt MRTS+Metro integrated station.

BEML expects Rs 100-200cr order before March 31 (http://www.moneycontrol.com/news/results-boardroom/beml-expects-rs-100-200cr-order-before-march-31_438853.html)

Q: Could you also give us an update on your MoU with SAIL when would you see the production of the wagons getting rolled out, could you give us a timeline?

A: I also wanted to tell you that we have been pre-qualified for the Chennai Metro Corporation. We are going to quote for the tender. We are also one of the contenders of the Hyderabad Metro. Hopefully, we should get qualified. All these metros coming up are going to be engines of great growth. We should be crossing Rs 1,000 crore in the registry of the company.

We have signed up with SAIL for producing country’s first 100 tonne stainless steel wagon. This product is going to be offered to the high speed freight corridor. Before the corridor is opened, we are ready with the product. We have already rolled out the 80 tonne bottom discharge open type aluminum wagons in collaboration with Nalco and maybe in first quarter the 25 axle wagon will be rolled out in the country for use.

CMRL updates metro map.

Main change - Ashok Nagar & KK Nagar stations are combined into a single station.

Arul really I lost all hopes about Chennai Infra.
Alll sorts of clearance problems even a small 3 kms road project no progress for years :bash:

But we have to see how MRTS and Metro coordinate on St.Thomas mt MRTS+Metro integrated station.

given the poor record of MRTs it wont work well I am afraid. This is why I always suggested a rethink of the routes. MRTS between Velacherry & St THomas Mt shouild have been taken over by Metro for an expansion of the Thirumangalam to St Thomas section all the way to Velacherry or Thiruvanmiyur... given the sheer volume of traffic that flows from West Chennai to ECR or ITE :(

FINALLY,when i was waiting for my college bus after almost a fortnight, today near the SAF Games Village Koyambedu; i noticed something different in the construction area of the CMRL. i was surprised to see the metal rebars or whatever you call it jutting out of the barricade. it is arising from a huge pit. and they have dug two more equally big pits on either side of the existing bars(rods). the rods are very thick and from how the rods are placed, i think the pillar is going to be very wide. anyways hope to see more developments on this stretch from now on. :banana:

^^ Even I saw the rebars being readied to be put up few days back when I travelled thru IRR. Good to know they're turning up.. I guess the foundation work is almost over now :-)

Guys,
does any1 know the route of the metro from Ashok pillar to st.thomas mount? r they planning it via kasi theater,olympia tech park,kathipara ?

Here comes the official press release confirming the award of contract to L&T.

I guess Prime Minister will be Inaugurating The metro rail work when he comes to chennai for inauguration of new Secretariat on march 13. after tht only i think the work will pick up. but i dont know why our deputy CM is not taking any interest in metro work when compared to other infrastructure works.

Hopefully we should have a Indian manufacturer for Chennai metro coaches. This should set an example for other future metros

This seems to be the trend now. Some of Delhi Metro's SG coaches as well as Bangalore Metro's coaches are being manufactured and supplied by BEML. Also, with more metros coming up in various parts of the country, the market for coaches has really opened up - Bombardier has already set up its manufacturing unit in the country. So Indian manufacturer or not, most future coaches will probably be manufactured in India.

^^ Kolkata's metro trains were also manufactured by (ICF) Integral Coach Factory and I think their new trains will be supplied by the same manufacturer.

ANother inauguration and how many?. Already the PM laid foundation Port expressway not yet started and not yet got the environmental clearance.

:ohno:

According to Wikipedia

The first section to be opened will be on Line 1 between Teynampet and Airport and this stretch would be in operation as early as 2011.

with just less than 1% progress i see this Chennai Metro to be completed in 2025. going by the way they constructed MRTS

^^ Immense political will (like MK's on the new legislative assembly) or pressure to meet a deadline (like the Delhi Commonwealth Games) is needed to get such big projects done on time in a country like India. In the absence of these two, people must endure all these. Atleast hope that the future generation in India will have access to better infrastructure by the time they grow big (20 years from now on) :lol:.

Most of India big projects are done within 150% of the original proposed timeline. Only in Chennai any infra project takes at least 1000% of proposed time or some MOEF comes and stops the project.
In other cities of TN according to me so far no big infra projects was every proposed or executed except for some jujupi projects like airport expansion and before completion of this project I hear ridiculous words like "Trichy airport is overcrowed" etc.:bash:

You are right for the most part if not fully. Chennai has lost its shine after the rise of B'lore and Hyd in the past 15 years. Although the political climate in TN was a lot more stable and solid compared to those states, they didn't transform it into real economic growth. If Hyd hasn't been hit by the recent Telengana issue, it would have gone ahead with its major projects like the metro. I feel Chennai is only playing catch-up with other cities in terms of economic and industrial growth :ohno:

Anyway, its good that Chennai Metro work has started and reached a point where our Amma (if at all they come to power next year) won't stop it quoting monorail as the alternative.

Lets hope for the best. Please do post regular updates. I am loving to see those pillars coming up :)

^^^^^^
Joke of this year...

I feel Chennai is only playing catch-up with other cities in terms of economic and industrial growth.

Genius reason of the year....
If Hyd hasn't been hit by the recent Telengana issue, it would have gone ahead with its major projects like the metro. :nuts:

dude get some timeline...think yourself.
Telegana issue born with state AP
YSR dead Sep 2009
KCR started telengana issue again Dec 2009

from Jan 2010 Telengana issue gone wild...

Do you need reason for HYD metro delay? its Maytas

^^ Maytas has affected Chennai MRTS too. Let me quote you some projects completed in Hyd - new airport, elevated flyover to the airport etc. You know the situation of Chennai airport. That is why I said catch-up.

We have another 2 or 4 years for atleast the first phase project to be done. We can argue, fight...err...have an 'intellectual discussion' for the rest of the those years too :lol:. Lets not waste our energy now itself. :)

Tenders up for Elevated Stations

1. Corridor 2 (http://chennaimetrorail.gov.in/EAS-04.htm)
Koyambedu, CMBT, Arumbakkam, Vadapalani, Ashok Nagar/KK Nagar stations including integrated viaduct + flyover @ Vadapalani

2. Corridor 1 (http://chennaimetrorail.gov.in/EAS-05.htm)
Little Mount, Guindy, Alandur, OTA and SIDCO stations

^^ Completion time of these station works is 1095 days.. so the deadline is clearly 2013 for Elevated sections too.

Also Pre-qualification application for track works advanced (http://chennaimetrorail.gov.in/Corrigendum_ATA-01.pdf) to 15th March from 7th April.

Kewl....How far is the progress on the Corridor 2. We had images showing the ground works....any updates after that?

^^ Completion time of these station works is 1095 days.. so the deadline is clearly 2013 for Elevated sections too.

Also Pre-qualification application for track works advanced (http://chennaimetrorail.gov.in/Corrigendum_ATA-01.pdf) to 15th March from 7th April.

So you mean the first ride on Chennai Metro is not before 2013?I saw some 2011 deadline somewhere.

Realistically the first phase of one line that is elevated only will get over by end 2014 or early 2015 that is my predication.

So you mean the first ride on Chennai Metro is not before 2013?I saw some 2011 deadline somewhere.

2011 was the deadline (MKs deadline eyeing elections). Guess it must be 2013. I suspect something for their slow progress.. (ofcourse something good). :)

Also, the tenders for design and procurement of cars is not up yet. We can expect all major tenders to be up (including the underground section) sometime till may/june 2010.

Today saw many number of pillar shaped meshes near SAF games village.. dont know their exact name .. there was around 10 meshes stacked one over other .. :)

And two were already fixed to the gorund .. ready for pillar construction work ... :banana::banana:

Metro Rail to build flyover at Vadapalani
V Ayyappan | TNN

Chennai: It will be the Chennai Metro Rail, not the state highways department, that will build the flyover at its elevated Vadapalani station.
The highways department originally planned it to decongest Jawaharlal Nehru road (100 Feet Road) - Arcot Road junction. The 400m flyover has been included in a tender floated last week to build five elevated stations — Koyambedu, CMBT, Arumbakkam, Vadapalani and Ashok Nagar.
A Metro Rail official said, “We have decided to construct the Vadapalani flyover because the structure will have to be integrated with the elevated corridors and stations being built by Metro Rail.” Though minute details of the design are yet to be finalised, Metro Rail is planning things in such a way that the flyover will also help commuters drive in and drive out of the station. The integrated structure will have car parking and roadside drop-off zones through ramps.
Metro Rail will also soon start examining the projects planned by the highways department along Poonamallee High Road that falls in Corridor Two — Central-St Thomas Mount — based on applications submitted by the authority for clearance.
“We will have to clear all projects planned along the Metro Rail alignment. We have received a couple of applications for projects along Poonamallee High Road. A technical team will have to carry out a detailed study before clearing projects,” said a senior official of Metro Rail.
“Once all projects planned by other agencies
are cleared, Metro Rail will carry on with its construction works for which tenders have been awarded to Soma Enterprises and Larson and Toubro to build elevated corridors,” said the official.
With works progressing rapidly at different locations on 100 Feet Road, Metro Rail has also floated a tender to identify builders for five more stations - Little Mount, Guindy, Alandur, Officers Training Academy and SIDCO industrial estate of Corridor Two.
L&T has already bagged a contract to design and construct the 4.56km-long elevated viaduct from Ashok Nagar to St Thomas Mount at an estimated cost of Rs 141.13 crore and the 5.17-km stretch from Saidapet to the OTA at Rs 173.30 crore. Soma Enterprises has already started works on the elevated corridor from Koyambedu to Ashok Nagar.

Halda junction is dropped i believe. Coz they have plans for an elevated road and monorail in tat road (if both these projects take off, it wont require a flyover)

I'm sorry to ask about Chennai suburban in this thread but thought it is all part of the overall mass rapid transit system being built in Chennai. Will the MRTS line extension under construction to St. Thomas Mount be terminating there or will it join the Chennai-Chengalpet line as a branch? Also, does anyone have any info on how the two suburban lines and the metro corridor 2 be integrated at St. Thomas Mt?

All are separate systems. Nothing is gonna merge with anything. All three will be integrated at STM, thats it.
Ground level - Suburban
First level - MRTS
Second level - Metro

cool...will look forward to see this station in operation.

If you're interested, I believe a rendering of this 2-level station was posted on an earlier page of this thread..

Nothing happened in this project for past 4months. Looks surely the dead line will be missed for elevated corridors. :bash:

Halda junction is dropped i believe. Coz they have plans for an elevated road and monorail in tat road (if both these projects take off, it wont require a flyover)

Chennai Monorail? Are you serious? Has there been any serious talks about it?

^^ I said, there's a proposal. Thats it. Nobody knows whether they'll even think about going ahead with it.

^^ I said, there's a proposal. Thats it. Nobody knows whether they'll even think about going ahead with it.

There was a proposal in 2006 for a 300 KM mega monorail netwrok to be established in a single phase. But it was quashed cos for such a big city it can only act as a feeder but not as a primary PTS. So i was wondering if it is coming back in a new avatar. It would be really gr8 to see them doing the feeder transportation in Chennai.So as such I dont see any such plan as of now.

^^ We have two monorail corridors planned in Master plan 2 prepared by CMDA during DMK's rule. :)

^^ Thanks guys :).. thats the simple thing i can do :P

Great Job KB,

Any idea what the ticket fares would be like? I was looking at the Delhi metro thread, the trains and station looked very well maintained. Hope to see the same repeated in Chennai.

this is great!

great work by kewl :cheers: what is the real deadline,is it going to be another mrts dragging till 2018 or above:bash::bash:

great work by kewl :cheers: what is the real deadline,is it going to be another mrts dragging till 2018 or above:bash::bash:

I got it confirmed by the CMRL by mail (surprising).It is 2013-2014.IMO there wont be such delays for this project.

Kewl, nice try indeed. Appreciate your enthusiasim. But are thesse based on actual plans or your imagination ?

^^ Thanks guys.

They're the actual alignments and location referred from CMRL tender document.

And, to others who feel the project is delayed, it is not delayed by even a day AFAIK.

Kolkata metro tenders were putup/awarded in september 2008 itself, tats y u see more progress in Kolkata metro. But CMRL awarded 1st tender in feb 2009 only.

Awesome work Kewl... Any ideas about how the St. Thomas Mount station would look like?

Guindy Station

Good opportunity here to integrate with the suburban station.

There is a mall which is coming up near guindy, i guess it is express avenue, if they way a walkway to Metro underground i am sure it will attract huge crowds.

No buddy .. there is BSNL and Police colony there ... may be they will try out the kalyana mandapam opp to udayam theatre for station land ..



There is no chance that they will take that playground as it is Police training ground !! :cheers:

Thanks dude. :)

They merged Ashok Nagar and KK Nagar coz they were planned too close to be efficient. And the station is planned exactly (+ or - 20% :D) where I drew it. It wont touch the play ground AFAIK.

They've also deleted Indian Airlines Colony Station from the plan. Most of the stations are very well planned so that they are integrated with MTC, Suburban, MRTS and other modes. :) Also Kathipara is gonna be a major interchange in future. We need few more pedestrian subways in there.

f.y.i

Am not sure if those renders are still valid for St. Thomas Mount and Airport terminal station. Coz they were designed for 3rd rail system. Now that we're going in for overhead catenary system, they might redesign it or juzz alter the dimensions. So can't say.

great work kewl batty... would u pls. clarify this.. by seeing vadapalani, station entrance seems to be not parallel to 100 feets road.. its seems to be samewhere injecting from east(arcot road)?

exactly.....i am extremely disappointed with CMRL for zeroing in on such lousy designs, when they could have been made ultramodern and trendy. and first of all i cannot understand as to why they changed their plan of having a third rail and instead opted for the overhead cables.

these designs have given me a nightmare as they have a startling resemblance with an existing eyesore of Chennai, The Great MRTS. I just hope the stations does not turn as lousy as the the MRTS. i am praying to god to give our CMRL authorities a good mind and some brains to think and come up with some good designs.

at least can't they think of different designs??? are they so intelligence deprived that, all they could come up was with different versions of the same design. they cannot even be called different version, all they seem to have done is change the tips of the metal cladding roofs of all the stations with a few exceptions. the core design of all the stations seem to be the same.

and initially, when vadapalani station was planned, they said that there would be entry/exits from all 4 sides of the junction. but that seems to have vanished in the design. plus as pointed out above, the alignment of the vadapalani station seems to be perpendicular to the 100 feet road. i thought that the flyover was to come up on arcot road. but if the render is correct, then the flyover must be built on 100 feet road, which according to me will not be feasible taking into consideration the space occupied by the station by the side of the flyover.

and in the renders of a few more stations(not able to recollect which) the alignment of the station seems to be perpendicular to that of the road.

anyways, thanks a ton kewl for your effort. at least let us hope that when a colored version of the renders is released, it may look pleasing. Let us hope for the best!!!!

three more points of discussion:
->if you notice, there is indeed an interchange facility proposed from the metro to suburban train at guindy.
->why are there three tracks for koyambedu station?? Is it for the Depot operations?
->is the depot not in cmbt station??

-> Yes, the corridor 1 is planned to be integrated with suburban at guindy.
-> Exactly, the third tracks is for depot.
-> The depot is not at CMBT.. but juzz across CMBT next to koyambedu station. Does that make any difference? :?
===

I guess there's are juzz preliminary designs and facilities to be provided. As the tender is for Design and construction, I guess we can see some changes and good renders. Lets wait :)

Since these are juzz prelims to give an idea about the proposed facilities, we don't have to worry abt them. The actual renders we can expect around the end of this year! :)

One more thing is that since we Chennaiites are already used to MRTS kinda thing (though poorly maintained), we won't find Metro that amusing! Juzz my thought.

hi mr.kewl batty, really appreciate your great work.

Am not sure if those renders are still valid for St. Thomas Mount and Airport terminal station. Coz they were designed for 3rd rail system. Now that we're going in for overhead catenary system, they might redesign it or juzz alter the dimensions. So can't say.

Are you sure they r going for the overhead catenary system? The project detail document in their website still says its a 3rd rail?
I dont like those overhead ugly structures ona metro:ohno:

^^^^

Hey Kewl ....thanks for uploading the plans!!!
It will be great to see these structures in reality!!

Don't know how far this news will reach the project planners....Its better to start constructing them in Parallel Phases.....And not going one construction after another......

Are you sure they r going for the overhead catenary system? The project detail document in their website still says its a 3rd rail?

3rd rail is poses a risk for commuters. If somebody falls on platform or if there is a need of emergency evacuation in middle of the tunnel or viaduct, then 3rd rail can be disastrous. Also 3rd rail is more costly in long run (though cheaper in installation) and cannot support higher speeds.

true , I for one would rather compromise a little bit with asthetics than on commuter safety.

Recently there was an incident in Delhi metro ( if I recall correctly) when the train came to a stop in the middle of the tunnel and panicked passengers forced open the doors and walked out of the tunnel. Had there been any 3rd rail , the poor souls would have been fried.

It's not such a good idea in India , atleast not right now.

^^ though i guess they could get creative wit the way those things look... maybe make it look less... obvious??

Any cannot be concealed by any means ;) haha.
@ abhishek: I dont agree that the 3rd rail will not allow to speed up. IT can safely let you reach 90-100 kmph good enof for a city commuter. But I agree with the safety issues for we indians delight to get down on the tracks:lol:

For the Alandur Station, The platforms initially planned were island platforms and that made a lot of sense. now in the renders the platforms are depicted as side platforms. (and just FYI from the station details given by CMRL initially the upper deck is for corridor 2 and the lower deck is for corridor 1).

if the station is as per the renders, suppose a person from St. Thomas Mount wants to go to airport, he reaches the second level of the station. if then comes to the first level of the same side then he will be in the direction towards washermanpet. so he will have to go down one more level (the level below both the platform levels) and then cross over to the other side and then again come up one level.

and afaik, small FOBs are not possible inside the stations because of the overhead cables. if the island platforms were used, this problem can simply be eliminated. what say??? correct me if i am wrong...

I have seen third rails in many places with a shroud on the top and one side. It is quite safe unless a person purposely puts a hand or foot under the other side of the cover

whats the difference b/w island platform and a side platform :?

an island platform is a platform that is in between two tracks. in this case the passengers traveling on both sides of the metro can alight and board from the same platform. here are a couple of pictures:

http://upload.wikimedia.org/wikipedia/commons/6/6d/Beecroftstationsyd.jpg


on the other hand side platforms will always be as a pair with one platform exclusively for trains in each direction. Here is a picture:

^^ cool :cheers:

thanks a lot coolmukund :)

3rd rail is poses a risk for commuters. If somebody falls on platform or if there is a need of emergency evacuation in middle of the tunnel or viaduct, then 3rd rail can be disastrous.

It's not going to be disastrous if someone falls on the platform...problem would arise only if someone fell off the platform onto the tracks :)

Even in such a situation, the danger would not be very significant because the 3rd rail is placed on the outer edge of the tracks (i.e. the edge away from the platform). This is exactly what is done on the Kolkata Metro. And the few people who have committed suicide there have died by coming under the wheels of the train and not in contact with the 3rd rail.

Also 3rd rail is more costly in long run (though cheaper in installation) and cannot support higher speeds.

Metro will probably run at 80kmph max., which I think 3rd rail shouldn't have a problem supporting. This isn't a 135kmph Delhi AE - type line.

Recently there was an incident in Delhi metro ( if I recall correctly) when the train came to a stop in the middle of the tunnel and panicked passengers forced open the doors and walked out of the tunnel. Had there been any 3rd rail , the poor souls would have been fried.

It's not such a good idea in India , atleast not right now.

In that particular instance, if I remember correctly, the train came to a halt because of power failure. So the question of danger to passengers would not arise. In any case, power supply can always be shut off before undertaking any rescue or evacuation operation.

Nobody would travel from Velachery to Airport by changing 3 trains. Rather they can take up the IRR and reach airport quickly :D

Can't even think of someone from STM requiring trains to go to airport! they don't normally take public transit, its juzz 5 mins drive and if ppl from STM wants to go to airport by train, they can use suburban.

that is fine... normally people wont do it.... ok so lets take it like this. i am coming from airport and my house is very close to STM station. it is late in the night and at a time when metro operates too. so i dont want to disturb my family and decide to take the metro home. in that case my question would be sensibe??

my point was at interchange stations like these, island platforms would be better for the reasons mentioned in my earlier post. the situation in my earlier post was just an example to make people understand my point...:)

^^^^ At alandur I think will be the first double decked metro station in India:banana::banana: This is xatly how an interchange should be. I hope they dont change it by any means.

if the station is as per the renders, suppose a person from St. Thomas Mount wants to go to airport, he reaches the second level of the station. if then comes to the first level of the same side then he will be in the direction towards washermanpet. so he will have to go down one more level (the level below both the platform levels) and then cross over to the other side and then again come up one level.

and afaik, small FOBs are not possible inside the stations because of the overhead cables. if the island platforms were used, this problem can simply be eliminated. what say??? correct me if i am wrong...

Yeah. They should have built island platforms for convenience of commuters. But FOBs are possible over the OHE wires. See here in Delhi's Rajiv Chowk station. This is a double decker underground station and the upper level has side platforms and lower level has island platforms. So there is an FOB at upper level to cross over the tracks.

Here you can see both, the lower level and the FOB.

I have seen third rails in many places with a shroud on the top and one side. It is quite safe unless a person purposely puts a hand or foot under the other side of the cover

Indians can even do that :lol:

It's not going to be disastrous if someone falls on the platform...problem would arise only if someone fell off the platform onto the tracks :)

:D

In that particular instance, if I remember correctly, the train came to a halt because of power failure. So the question of danger to passengers would not arise. In any case, power supply can always be shut off before undertaking any rescue or evacuation operation.

What if there is another problem or a bomb blast ? People may try to rush out and step on the third rail. People many times do not wait for help. In that instance train operator asked the people to stay inside the train through public announcement system but people still decide to show their bravery and opened the emergency gates and stepped out.

^^^^ At alandur I think will be the first double decked metro station in India:banana::banana: This is xatly how an interchange should be. I hope they dont change it by any means.

Not at all. Delhi has one. Bangalore will have one soon.

It's not going to be disastrous if someone falls on the platform...problem would arise only if someone fell off the platform onto the tracks :)

Even in such a situation, the danger would not be very significant because the 3rd rail is placed on the outer edge of the tracks (i.e. the edge away from the platform). This is exactly what is done on the Kolkata Metro. And the few people who have committed suicide there have died by coming under the wheels of the train and not in contact with the 3rd rail.



Metro will probably run at 80kmph max., which I think 3rd rail shouldn't have a problem supporting. This isn't a 135kmph Delhi AE - type line.

Sorry if I am posting a very basic question. Can someone explain what does a 3rd rail means? Just to understand the discussions ongoing here. Thanks.

A third rail is a method of providing electric power to a railway train, through a continuous rigid conductor placed alongside or between the rails of a railway track.

Other method for traction is overhead electric wires which we see in IR lines.

Hi everyone,
This is my first post. Long time lurker though. I sent an email to CMRL on the shocking station designs and here is the response I got.

Dear Sir,

These are the preliminary & temporary draft designs.
The contractors (consultant architects) are to
develop their own design and submit the tender.
we hope that tenderers will submit modern
designs, as you expect, during their submission.

For Chief Public Relations Officer,
Chennai Metro Rail Limited.

^^ Welcum to SSCI. :) Thanks for your effort in mailing them!
yup, they're prelims. The tender itself is for design and construction. :)

I posted those drafts here so as to have an idea on the location of the stations and basic features to be expected from them!

Sorry if I am posting a very basic question. Can someone explain what does a 3rd rail means? Just to understand the discussions ongoing here. Thanks.

Next time when u take the MRT (North south and the East west) look for them on the side of the parapet walls.

Hi Mugu,

Thanks. I haven't taken the MRT for quite some time. Will look for the 3rd rail when I travel next time in MRT.

When will L&T commence construction work ..I havent seen any news or work on commencement of the work.:ohno:

Still no pillars up???:ohno:

i guess since there is election coming up next year, there will be some action coming up in couple of months.

Still no pillars up???:ohno:

the pillars are not yet up. but the metal bars meant to be the skeleton for the pillars are up in the SAFGV site. in fact Four of them are up now. from now we can see some amount of visible work happening...:)

Last weekend , i saw the soma work site in vanagaram near fish market. A huge site with all kinds of machines huge cranes, concrete mixers, dumpers etc. They are huge metal skeletons to case concrete super structure. I think they are waiting for these super structures to be ready before erecting the pillars. Once the structures are ready they put in the pillar and the super structure over them and move ahead . But there is no sign of L&T metro work site. Do you guys have any news where L&T is going to have the metro work site

Just now I saw CMRL ppl conducting land survey outside my office on the Jawahar Lal nehru road in ekkatathungal(ambal nagar).On querying they said that soil and pile testing is suppose to begin by mid april along the stretch...:banana:

Hope this project gets started as quickly as possible...

Just by these kinda news this thread crossed 1150 posts. :popcorn:

^^ one should be happy to c the amt of discussion even before the commencement of services.

who is the "one" that you are talking about. He seems to be very popular. "one" should be happy, "one" should not worry, "one" should exercise to be healthy... :)

Sorry! Just harmless fun at your expense.

Anyway, I am posting to tell every chennai-ite that their behaviour is mockingly selfish and unacceptable!!! I cannot wait anylonger!!! Where are the photos?

^^:lol:
leave him those who put details of what you saw,can put photos of that super structure or whatever progressed till now

Short translation:

1. Soil testing completed for 4.5KM from Koyamedu to Ashok Pillar
2. Pillar works started for the same section
3. Concrete slabs casting also started it will be transported to site through lorries on due course.
4. And to place the concrete slabs, the cranes were imported from China and this is assembled right now near Koyamedu 100 feet road. :nuts:

good..hope we can have a metro in another 3 yrs.

Only after piling then they can start puttin up pillars, right? ;)

Yeah. And my above post states that you shouldn't expect me to know all the technical things :)

Yes, piling has to complete before the construction of pillars/ columns. But, most of the time the works are phased. I mean, once piling is completed over a considerable stretch, the column construction can commence. In the meanwhile, the piling works would go on at other places. Since, each contract is about 5km, the contractor should be able to progress works in phases.

Apart from the four metal columns that have come up in the SAFGV site for pillar construction as stated in my earlier post, two more have come up in the Vadapalani site in front of Ambika Empire Hotel. Work is going on at a visibly fast pace in the 5 km stretch from SAFGV to Ashok Nagar where the works began initially. they have dug pits to erect the metal columns in Ashok Nagar site also.

now if only we could get a picture confirmation fro someone then it can be safely said that the much needed Mass transit system is u/c in 5 out of India's 6 most important cities.

FYKI, Mass transit system exists already in Chennai. Suburban is more than 4 decades old and MRTS is nearly two decades old. Metro form of MRTS is new to Chennai.

Suburban 4 decades old? :?

It'll become 8 decades old by 2011. they started suburban in 1931. :D

1 more tender up. - Koyambedu Depot Filling

Also 2 more PQ for Signalling, Platform Screen doors & Telecom, lifts & escalators are up.

120 lifts and 300 escalators :)

Good that they're going for platform screen doors right from the beginning! :cheers:

Also I got this from one of the documents.

Project Implementation
The bringing into service of the Metro will be in two distinct phases:
a) Operational Passenger service will commence in 2013 for the Elevated Station sections of Corridor 2 and will include the commissioning of the Depot and Operational Control Centre.
b) The remaining line sections involving the sub-surface stations of the corridor 2 and the corridor 1 will be brought into operational service in February 2015.

yeah, I know that and I guess I should have specified "Metro". Metro is simply in another league compared to MRTS or suburban trains in relation to Speed, comfort and overall cleanliness.

I have seen some of the pictures of those MRTS stations and the less said the better, the people of chennai deserve a first class metro network which covers most of the city and suburbs.

Hey Kewl,
are the screens going to be like this (full height)
http://img638.imageshack.us/img638/6424/768346singaporemrtsinga.jpg

Does Bangalore metro have this?I dont think Delhi has it in all stations?

Its really a cool feature in many aspects.

And about the operationalisation I had enquired with the CMRL by mail and I was replied(Surprise- some good officers at work) that no service is starting before 2014.

Thats is really very good. Do any other metros in India planned for that amenity? 2013 looks to be optimistic one. 2015 we may get elevated part.

Yes the new East-West metro line u/c in kolkata is using Platform screen door. It will save the daily commuters from the pain of suffering delays when a blokehead moron chooses the metro tracks for suicide.:colbert:

Hey this screen door is cool .. i havent seen these before!!

how do the passengers know that the train is approaching ? bfore doors are opened ..?

Hey this screen door is cool .. i havent seen these before!!

how do the passengers know that the train is approaching ? bfore doors are opened ..?

you will obviously fell the train arriving by the vibration it causes to the structure and also by the light of the train and the lights inside it.

such screen doors are common in Singapore and Malaysia and in many other metros around the world.


It is a very good concept indeed and will be very useful for the exorbitant Chennai heat.
Having the screen doors will help provide effective air conditioning on the platforms.
It will help prevent the rule breakers and miscreants from crossing the tracks and doing all unwanted stuff on the track like urinating, spitting and all other nonsense.

Am glad that CMRL has decided to implement the screen doors. Hope it is implemented in all the stations of the Chennai Metro, especially on the elevated stations. this will provide a good escape from the heat even when you are standing on the platform.

And about the operationalisation I had enquired with the CMRL by mail and I was replied(Surprise- some good officers at work) that no service is starting before 2014.

i am actually surprised that so many of you are recieving replies from CMRL. well i had sent three mails to CMRL (2 inquiries and 1 request) and i have not received a single reply yet. Unlucky ME!!! :(

Thats is really very good. Do any other metros in India planned for that amenity? 2013 looks to be optimistic one. 2015 we may get elevated part.

In Delhi metro, only the Airport Express has platform doors.

Hey this screen door is cool .. i havent seen these before!!

how do the passengers know that the train is approaching ? bfore doors are opened ..?

Its transparent man. Moreover there must be passenger information systems telling about the time between atleast the next 2 r 3 frequencies.
So no problem.the One and only disadvantage is..you cannot have a uninterrupted look of the Coaches but ofcos if they r so aesthetically designed, my inner voice says chennai metro wont be one such :lol:and will be just like delhi metro coaches in terms of looks.Any way lets hope it looks sleek and elegant.HOPE!!!

Hey Kewl,

Yes the Platform Screen Doors are gong to be Full Height but only for the underground stations and not for the elevated stations. :gaah: :ohno:

The Outline Description of Passenger Screen Doors (PSD) in Tender Document ASA - 01 states :

" Full Height Platform Screen Doors including interfacing devices with CATC and associated monitoring and control devices will be installed, as applicable in all platforms of all underground stations."

It would have been very useful if it was extended to the elevated stations as well. Alas we were never and will never be pampered with all the comforts and facilities in one go without any problems!!!! :(

but yeah, something is better than nothing.

^^

And hey, if possible, all the lucky ones who have got replies from CMRL, please send a mail to them requesting them to extend the Platform Screen Doors (PSDs) to the elevated stations as well, as it will help the passengers to get respite from heat even while waiting on the platforms and also for the other advantages mentioned in Post No. 1177 (http://www.skyscrapercity.com/showpost.php?p=53416785&postcount=1177).

and also please tell me the mail id to which the email has to be sent to. i have sent mails to chennaimetrorail@gmail.com, but never received any replies.

but yeah, something is better than nothing.

Generally, the full height platform screen doors are provided only in underground stations. This is to serve as a safety barrier preventing people from accessing the tunnels, to save energy in providing air-conditioned stations and also to minimize the pollution by separating the tracks and the station.

For elevated stations, only half-height platform screen doors (HHPSD) are provided for safety purposes. Chennai Metro should provide HHPSD in elevated stations to prevent accidents. With the crowd in Chennai, it will be good to have safety barriers.

In Singapore, they had PSDs in underground stations since the 90s (or may be late 80s). But, the necessity of PSDs in elevated stations was only realized recently. With the increase in population, people are getting desperate to get into the trains. The number of accidents had gone up in the recent years. So, all the elevated stations are being fitted with HHPSDs now.

Will there be commerical malls in the metro stations. Or will they construct small shops like MRTS will remain closed. They can even have a multiplex in those stations or a multi floored office building where the metro arrives in the first floor and car park in the basement

Extension of Metro Rail Project to Tiruvottiyur under Study

CHENNAI: The State Government will construct grade separators at intersections on Anna Salai in the city, to ease traffic congestion, at a cost of Rs.500 crore utilising the resources of the Chennai Metropolitan Development Authority (CMDA), Finance Minister K.Anbazhagan said here on Friday.


Presenting the budget for 2010-2011, he said: “A comprehensive study conducted by the CMDA on transport scenario in the Chennai Metropolitan Area has recommended provision of various transportation facilities with an investment of Rs.88,200 crore.”


“In accordance with these recommendations, the government will consider augmenting the transport facilities in Chennai Metropolitan Area in the coming years,” he said. After the six laning of Rajiv Gandhi Salai, works for grade separators at its major junctions will be taken up at an estimated cost of Rs.171 crore. A sum of Rs.165 crore has been allocated for development of the Singaperumalkoil-Oragadam-Sriperumbudur Road.


On the Chennai Metro Rail Project, he said that the feasibility of extending the project to connect Tiruvottiyur was being studied. A provision of Rs.600 crore has been made in the budget as the share of Tamil Nadu government towards the Metro Rail Project, the Minister added.


Pointing to the fact that Tamil Nadu was the most urbanised State in the country in terms of the percentage of urban population, he said “The government has been implementing various schemes, recognising the need for providing infrastructural facilities commensurate with the increasing population in urban areas.”


The government is implementing two major desalination projects, at Minjur and Nemmeli. “A sewage treatment plant with 120 million litres per day capacity will be constructed at Koyambedu at a cost of Rs.130 crore in the coming financial year. Works for stormwater drains and flood protection in Chennai Corporation sanctioned at a cost of Rs.1,447 crore will be completed in three years,” Mr.Anbazhagan said.

ps: I have changed the Heading... sorry for misleading...

^^ The heading is misleading i think... 600 crore has been allocated for the Metro on the whole... not just for extension to Thiruvottiyur

Yes, that is correct. Here is the link to the actual article: http://www.hindu.com/2010/03/20/stories/2010032063450300.htm

I guess folks will have to wait a bit longer to hear about the extension...

Saw small barricades put up by L&T for Metro at two places in the median of IRR at Ekkattuthangal. I think they are meant for soil testing in these places.

One metal beam looks round and other rectangle... Are both different?

No dude if u c the top of the beam metal work .. u can notice the steel bars are even at 45degrees to the horizontal .. its like a curvy profile .. so it is the same circular metal work :)

Well this is what I could observe. I coloured the side with 2 lines. See the red line and blue line at the top. You can see that both red line and blue line are straight and they make an angle to each other. This can happen (lines being straight and making an angle) only when the column is rectangular.

http://img265.imageshack.us/img265/4664/20100318a001101008.jpg

Also see the area which I have marked in red and blue circles below. In the red region, you can see that all the vertical bars/rods seem to have a lot of horizontal space between them, which is constant throughout the red region. While in blue region, all the vertical bars do not have enough horizontal distance. If the pillar was circular, then the transition between red and blue would have been gradual, that is, the horizontal distance between the rods would have gradually decreased from red region to blue region instead of suddenly dropping at the edge. This again goes in favour of rectangular columns.

Anyways our eyes can cheat us :)

This is my understanding. The circular reinforcement cage, which is shown in an earlier picture, is for the piling works (foundation works), whereas the picture you are referring above is for the column (above ground, superstructure works). They are different.

exactly, the circular ones are for piling work and are being used for a long time. in fact i have even mentioned about the circular pillars in one of my posts three or four months before. i mistook them for pillars but later realized that they were for piling work.

^^ One good thing evident from the above picture is there is some consideration for the safety, I see all the workers wearing hard hat, reflective jackets with a rope attached to it.

So there is two different pillar structures... Huh..I thought my eyes cheated me again.

More barricades coming up in Ekkattuthangal area.

^^ That's part of L&T's construction site, right?

^^
Yep.

Update of the project

1) First piller done near SAF village

2) 4 More piller in the making

3) piling work completed till MMDA around 12 to 15 pilers

4) Second piling group starting from MMDA has completed 10 pilers and 4 metal structures raised

5) Grider launchers arrived and is ready near CMBT bus stand. The blue colour metal structure.

6) Barricades near ekkathutangal for soil testing in 4 places erected by L& T

7) super structure casting work started in Soma site near vanagaram

5) Barricades in 4 places rain

Come fellas !
We need more pictures to see the progress. With all those camera phones we expect more pictures to show us the progress.

Progress seems pretty fast. If no other issues such as shifting of utility lines, any cases or anything like that, the work should progress pretty fast. We should be seeing lot of above ground progress soon.

ya, the metal sheets for pouring in the cast of the first pillar has been put up today. it was not there when i went through that place at 6:30 am today. But when i returned at 10:00, i was surprised to see the first pillar which was ready for the cast to be poured in. the first pillar will be complete in a couple of weeks time. and so will be the case for the remaining 4 pillar works at SAF Games site.

As arun82 said, the entire stretch of the median from SAF Games site till MMDA signal has been cordoned off for works. and so is the case for 95% of the stretch from aishwarya mahal till Ambica Empire. In the vadapalani site also the works for two - three pillars can be seen protruding out of the barricades.

Let us see if the TN government can help at least one public oriented project to finish in time, if not earlier or faster, without posing any obstacles or hassles (at least if not constantly monitor the project like they did with the TNLA). Only time will tell!!! But i hope for the best...

^^ Good to hear about the progress, would be better to see the same :) Friends, photos please.

NEW DELHI: Japan committed 215 billion yen (Rs 10,535 crore) for six infrastructure projects in India, including Phase II of the Mass Rapid Transport System (MRTS) for Delhi.

An agreement to this effect was signed between Finance Ministry officials and the Japanese Ambassador to India Hideaki Domichi.

The committed 215 billion yen would flow into the country in the next fiscal (2010-11) and the year beyond.

With this agreement, official development assistance from Japan will touch 3,116.81 billion yen (Rs 1,55,840 crore), making India the highest recipient of such assistance from the Far East country.

The agreement allocates 30.54 billion yen (Rs 1,648 crore) for the second phase of DMRTS.

In addition, 23.4 billion yen (Rs 1,146 crore) will go towards Calcutta East-West Metro Project Phase II, 59.85 billion yen (Rs 2,932.6 crore) for Chennai Metro Project Phase II and 90.3 billion yen (Rs 4,422 crore) for the first phase of a dedicated Freight Corridor Project of Railways.

Besides, three billion yen (Rs 150 crore) would be given for Rengali irrigation project in Orissa and 5.3 billion yen (Rs 263.8 crore) for a forestry project in Sikkim.

^^ Phase II financial confirmed already? But we yet have no details regarding the Phase II lines. :ohno:

Rs 1,55,840 crore :cheers:
Woow ... thats a lot of money ... but is it "assistance" bole to help/donation for developing India .... or a Loan which India is suppose to pay back in future ?

dude, no one will give such a huge sum for donation. It is a loan for infra projects in India.

Its a loan, but long term and very very cheep compared to the market rates!

Yesterday saw people doing soil testing on two spots-one on each side of the Adyar bank, west of the Kasi theatre bridge.

^^ Phase II financial confirmed already? But we yet have no details regarding the Phase II lines. :ohno:

is any one have details about phase - II ( length, location etc....)?

^^ It must be these 2 corridors with few changes/extensions.

Corridor-3: Ambathur Industrial Area (Mogapair) - Ring Road - Arcort road - Panagal Park - Theagaraya road - Eldams road - Luz Church Road - RK Mutt Road - Adyar Bridge - Lattice Bridge Road - Tiruvanmiyur

Corridor-4: Porur – Kodambakkam (Arcort Road) - Panagal Park - Theagaraya road - Eldams road - Luz Church Road - Kutchery Road - Kamrajair Salai

or it could be for this
Two corridors have been proposed in the comprehensive transportation study recently submitted by Wilbur Smith Associates

Corridor 1: Medavakkam — St. Thomas Mount
Corridor 2: Madhavaram — Lighthouse via Radhakrishnan Salai


if Corridor 1 is implemented as per the study, it will be big boost, but will overcrowd the trains, as it is 75% middle class -upper middle class people there.

but it has be underground, otherwise they will have to demolish hell a lot of houses.

^^ Nope, Those two come under CTS. They've not done project survey, soil testing, DPR, nothing for that yet. Juzz a proposal. And is just a recommendation in CTS to TN Govt. DMRC/CMRL has to take them up and prepare DPR.

Japan would sanction loan only when studies are completed. :)

Corridor 3 almost will run parallel to MRTS from Thiruvanmiyur to Luz, Southern railway may oppose that, it may affect their patronage. :nuts:

But yes we badly need MRTS or LRTS for 29C and 23C routes, If I am correct these routes will top the bus frequency in the city.

I use to see bus for every one minute near Isphaani Center near Anna Flyover. Corridor 4 is also badly needed.

And for these corridor where we have space? everything will be under ground? I feel better we need LRTS or monorail for congested areas like T.Nagar, Mylapore, Thiruvanmiyur etc.,

But i dont think LRT or monorail will be sufficient enough to carry the number of passnegers in this important route...only a metro can do that....LRT or monorail is useful only as a support service to the metro.

are there any pics of the rolling stock for the Chennai Metro ?

T Nagar certainly needs Metro connectivity in the next phase.

Ideally I would wish something like Porur to Light House via Ashok Nagar ( Line 2 interchange ), T Nagar , Teynampet ( Line 1 interchange ), Light House ( MRTS interchange ).

Its a loan, but long term and very very cheep compared to the market rates!

International assistance/loans Govt. to Govt are always on lower rates and the condition in the contract is that we have to give Japanese companies work into these projects.

hey is this mugappair to light house corridor thro west mambalam -ashok pillar ... ??

if this is implemented .. tnagar can breathe easy at peak hours :banana::banana:


btw how are they going to align the route thro densely populated tnagar and west mambalam :nuts:

is any one have details about phase - II ( length, location etc....)?

I have a feeling that the news article has incorrectly mentioned it a "Phase 2". It must have been the release of remaining funds already allocated for the ongoing Metro project.

There seems to be not much movement towards phase 2 in the planning circles. I'm not very hopeful that they'll start thinking about phase 2 even before phase takes some shape.

Vijay, i guess you got confused.

Phase 1 : two corridors for which currently the work is going on

then Other Phases src Wikipedia.

Corridor 3: Ambathur Industrial Area (Mogapair) - Ring Road - Arcot road - Panagal Park - Theagaraya road - Eldams road - Luz Church Road - RK Mutt Road - Adyar Bridge - Lattice Bridge Road - Tiruvanmiyur

Corridor 4: Porur – Kodambakkam (Arcot Road)Pangal Park - Theagaraya road - Eldams road - Luz Church Road - Kutchery Road - Kamrajar Salai

Corridor 5: Ring road

Corridor 6: Radhakrishnan Salai - Nugambakkam High Road- Mc. Nickols Road - KMC

Corridor 7: Along NH 5 Road

Its a loan, but long term and very very cheep compared to the market rates!

here is another thought on International Loan from http://www.rockford-india.com/foreignloan.htm

Here is a sample calculation in Financial Engineering of (LOW INTEREST!) FOREIGN LOANS, during the ten year period of 1985 to 1995, TO BE REPAID IN FOREIGN CURRENCY, with the following simplified assumptions :


Exchange rate of 1 US$ is nearly equal to Rs.11.00 in 1985
Exchange rate of 1 US$ is nearly equal to 205 Japanese Yen in 1985
Exchange rate of 1 US$ is nearly equal to Rs.35.00 in 1995
Exchange rate of 1 US$ is nearly equal to 110 Japanese Yen in 1995


ADVERSE EFFECT OF DEVALUATION MAY ENCOURAGE INVESTMENTS OUTSIDE INDIA AND IT MAY DISCOURAGE INVESTMENTS IN INDIA.

Assume average interest rates during 1985 to 1995 as nearly equal to 6.5% on (LOW INTEREST!) FOREIGN (US$) LOANS, SPECIFICALLY TO BE REPAID IN FOREIGN CURRENCY, and nearly equal to 12% on DOMESTIC LOANS.


Assume compound interest during 1985 to 1995.

When the (LOW INTEREST!) FOREIGN (US$) LOANS ARE REPATRIABLE, SPECIFICALLY TO BE REPAID IN FOREIGN CURRENCY, during the ten year period of 1985 to 1995, it shows an equivalent of nearly 20% in "Rupee Terms" (say, rate of annual Return on Investments, ROI, in INDIA).


What can be our century-old wisdom in (proudly!) announcing our (LOW INTEREST!) FOREIGN (US$) LOANS, SPECIFICALLY TO BE REPAID IN FOREIGN CURRENCY [say, at nearly equivalent of 20% and above in "Rupee Terms") as against our low interest (nearly 12%) DOMESTIC LOANS? Great Indian Sixth Sense : MISMANAGE! Are we still immature to understand it?

^^ I agree that its not all in our favour, but the above article is deff. not fair..

to be honest, it left out the below points

1) 1991 was a one of kind of a situation.. The exchange rate changed suddenly and very negatively! This was not engineered by the Japanese, but by our own mismanagement.

2) Domestic loans are fine, but did we have enough to go around? Who in their right mind would take the the currency risk if they had local sources? We do not have enough domestic sources of credit (especially in the absence of local bond markets for private players). So we have do go for loans from abroad and in that scenario, those loans re indeed cheap.

3) It is entirely possible that with the current scenario, the Rupee may appreciate against the Yen over the next few decades because of the economic environment and the dollar's slow decline. In such a case, the effect is reverse!

Kudos to Dinamalar, hope the turn their eyes towards Chennai AP project and IT Corridor project also.

Good to see pillar started to rise on IRR.



^^ It must be these 2 corridors with few changes/extensions.

Aaah, thanks for the update man! :) Can't wait for this to be done!

Could you translate the caption, please?

First pillar for construction of Chennai Metro in Koyambedu 100 feet road has been initialized.:)

:cheers:

yippee!!! the first pillar is up and done... in fact the pictures posted above in this page have been taken from above the first pillar. they are now removing the metal sheets from the pillar and going to begin the erection of the second pillar!!!!

:cheers:

Circular piers would have added to the aesthetics...

^^ You are right. B'lore metro's pillar design is awesome!

:cheers:

Wow! thats nice to see the pillars.
