Thanks for sharing, Bono. Seems to be a very detailed and complicated process.

cant understand whats the importance of this diaphragm wall.. is it like a compound wall in underground for metro tunnel?

i have a question.
don't they work on sundays???
or during day time???

i went to city on sunday and found no one working, there were only barricades and machines, no workers.

or has amma ordered the work to stop?????

Work usually happens at the night time. They slowdown once dawn breaks. Btw the gantry reached P/101 a few days back when I was in Chennai. Has it reached 100? Soma is agonizingly slow. They were supposed to complete the viaduct upto Koyambedu and Ashok Pillar in February itself!!

can you please give the source supporting ur statement that work on that stretch was to be completed by feb ?

The diaphragm wall or shortly called as D wall is basically a retaining wall which help construct cut and cover tunnel structure. As the depth of excavation (bulk) would be around 15 m for the construction of underground stations D wall is the solution. Normally D walls are 1m width x 6 m breadth and depth as required by design. D walls can be designed to have depths as high as 60 m also for multilevel metro stations. Bentonite slyrry acts as a stablising liquid which holds the trench from collapse until the d wall trench is concreted. Depending the soil condtion the whole operation starting from excavation of trench, chiselling or trimming, desanding, verticality test, stop end lowering, cage lowering and concretig may vary from 1 day to some times even 4 days. Based on the alingment and sequence of construction D walls are also labelled as primary panels, secondary panels and closing panels.

Generally for D wall constructions silo plants need to be set up which looks like a row of tall huge vertical cylinders which are 6 to 8 m. This can be seen from quite a distance away. Have they set up?

The one shown in the video is called Grab method. There is another method called cutter method in which stop ends are not used.


OK too much of litreature will be boring.

I just remember it. It was discussed in detail in this thread a few months back. You can browse back if you really want the source. Actually the tender was awarded in feb 2009 with a two year deadline.

I could only find the tender being awarded in the metro rail site on feb 2009. but nowhere its mentioned that it would be completed in 2 years.

It would be better if you can post the source from some leading daily.
Noone in CMRL has so far admitted that the project is being delayed. so i hope its on track .

It is in P/97 now.

Ok here is one. It says the work is to be completed in two years

Kewl Batty also mentioned it somewhere. You can browse the thread to see the conversation (and possibly some source). Ofcourse it is not going to delay the project. The Vadapalani station and the two tier overbridge construction is the biggest bottleneck right now. So even if the project is delayed, it wont be due to Soma. Anyway I have no hope of seeing a metro running before 2015 even in the elevated portions because

1. Vadapalani two tier flyover construction - This is a pretty complicated one and would take atleast another 2 years just for completing the viaduct let alone the rest of civil works.

2. Koyambedu yard construction - The tender was awarded in December 2010 and the deadline was 3 years. So it wont be ready before 2014.

3. Station works - Civil work has not progressed beyond the preliminary stage for any station.

Considering all these, i reckon the first trial run will happen only sometime in late 2014 and actual service to start in the second half of 2015.

It is in P/97 now.

Cool. That is some fast progress. But they are not consistent. Any idea what is the pillar numbering in SAF games village?

Here are some snaps that I took of the stretch between Saidapet and OTA. I had gone towards Tambaram. Some photos were taken while going towards Tambaram and some others on the return trip.

I understand that this is a very difficult stretch. But I'm not sure if the works are progressing fast enough to meet the deadlines. So far, the most difficult parts have not been tackled.

Cool updates Vijay and TD. L&T is atleast 6 months faster than Soma in all aspects.

How many spans have been completed in the Ashoknagar - St.Thomas Mount section?
How many gantry cranes are operating in this section?

Somebody pls answer.

http://chennaimetrorail.gov.in/newsletter/jun.pdf

Compared to May, the progress in all three elevated stretches seems satisfactory. 71/343 spans are completed as opposed to 53/343 a month ago. But they have to speed it up to around 30 spans per month so that the viaduct construction can end by summer 2012 and other civil works like parapet walls, track works, signalling, OHE installations can start (which will take another year to complete).

Two cranes are operating in this section. One is near Lords and moving fast towards Kasi theater. Second one is near OTP and moving towards Hiton. Will try to get pillar numbers soon.

I am fearing that the space between pillars could be occupied by huts in future.

Not fear but that is ur "divya drishti" ( ability to foresee :) ). And it's very possible in chennai n Mumbai in all probability.

Here's an idea. They should build 6-7 feet high grills/railings on either side of the pillar along the median. And then line it with creepers/vines. This will conceal the pillar up to a height which effectively renders them ineffective for potential advertising purposes. Protecting the railing from vandals/miscreants is a different story altogether.

Pillar construction happening on the adayar river after Kasi theatre. work on three pillars going on.

The skeleton of one pillar has come up and casting will start in a few days. The pillar on the river seems to be circular instead of the square format that we've seen so far.

Foundation is being filled with concrete for the second pillar.

Digginig is going on in full swing on the third pillar.

On the kasi theatre side, they are shifting all the utility lines just next to the adayar road bridge. I think, pillar work will start in a week or 10 days.

We may also see millagai bajjis hanging between the two pillars.

I am fearing that the space between pillars could be occupied by huts in future.

How millagai bajii and hut in the median? Now we don't have huts or milagai bajji's in Anna Salai or GST or PH roads or OMR. I expect following posters on pillars for sure........

1. kumudham
2. vikatan
3. nakeeran
4. pilles
5. rooms wanted
6. jobs wanted etc.,

along with huge banners for politicians!

during election time, kazhgams will share the pillars and make reservation like this

<-----------admk----------->, <----------dmk------------>, pmk, dmdk etc.,

This is common on walls! As the local election is going to be conducted by TN EC, there will not be strict rule like I EC! Posters ellam tharalamai oodum...

The corporation wall paintings may soon fall prey to local election.

This will conceal the pillar up to a height which effectively renders them ineffective for potential advertising purposes. Protecting the railing from vandals/miscreants is a different story altogether.

Good Idea Cant CMRL use the pillars for the same purpose for which the Vandalism happens. Advertising. Lease out all the pillars for 20 Foot advertisment on all sides. That will generate huge revenue for CMRL. Also where there is space put up a nice garden. Paint all pillars like Chennai corporation has done.

The highway department installed Designed lamp post in the GST along with palm trees. As the central median has been taken over by CMRL they mudt put some nice looking street lamps under the pillars not the normal ones.

^^ IMO, they won't be lamp posts but heavy duty lamps suspended from the viaduct. At least that's how it is in Bangalore's BETL. Or the lamp posts can be shifted to either side of the road (higher cost)

I like your advertisement idea too. It would be similar to how advertising was done on the Airport terminal's outer pillars, or old Chepauk's pillars.

Areas of concern.

Station work still not commenced

Not even soil testing commenced in OTA-Airport stretch.

CCCL has completed the pier for only 4 pillars.

http://www.faiveleytransport.com/

It has a plant in Hosur.

The CMRL report is pretty good. They should also include contractor wise performance. Am sure L&T is way ahead of Soma.

In the train image, they have cleverly avoided the overhead rod, the actual may be ugly with that :dunno:

^^ Well, obviously. OHT is ugly. Anyway the rake-renders are great.

What is "OHT"? OH=Overhead - what does the "T" stand for?

Maybe "transmission"??

transmission or traction?

^^ Either. I meant Transmission but Traction will do, too.

TRACTION...
OHT- OVERHEAD TRACTION

OHT = Over Head Transmission

I put overhead rod just because I don't know the actual name. :lol:

I put overhead rod just because I don't know the actual name. :lol:

What you were saying is pantograph, the device which collects current from overhead wires.

^^ pantograph is the part attached to EMUs, right ? The one that's retractable.

AFAIK, the poles are called Catenaries.

Yeah. He said overhead "rod", not "rods", so I am assuming he is referring to pantograph. I think he already has created lot of confusion :lol:

^^ pantograph is the part attached to EMUs, right ? The one that's retractable.

AFAIK, the poles are called Catenaries.

Catenary is an effect which causes the cables or wire(even chains) to sag to a curve shape when suspended (due to its own weight).

Poles are just referred as electric poles/posts.

Overhead transmission is a terminology used in electrical industry to denote that power supply is done above the surface usually by wires on huge steel pylons or even electric posts in a simple case.

Chennai metro will not use OHT they use a mordern method called as SCADA

(Supervisory Remote Control & Data Acquisition System (SCADA)
220 / 132 / 25 KV Power supply network for electrification extending along the track over a zone of about 200/300 km. is centrally controlled from the division control center through remote control arrangements to ensure un-interrupted power supply to the track overhead equipment. In the present day electrification projects, state-of-the-art microprocessor base supervisory control and data acquisition system (SCADA) is being provided as against the earlier electro-mechanical strowger system of remote control equipment. The SCADA system has facilities for tele-metering of voltage, current, maximum demand and power factor on a real time basis which enables control of maximum demand and thereby the charges thereof to be paid to the State Electricity Boards. In addition, this system provides for automatic trouble shooting and isolation of faulty section.)

OHT and SCADA are complementary not supplemantary. Both are the subsystems of Power Supply system. SCADA is an integral part of any power supply sytem. OHT or third rail can be used as power supply arrangement. In any case SCADA has to be used which is basically a controlling subsystem for power supply.

^^ So, SCADA is a kind of back-end system ? (Pardon me for putting it so vaguely)

I think SCADA is the monitoring system connecting various points and for automatic control of actions based on the monitored parameters.

We use SCADA in drinking water / sewerage management.

DMRC also uses SCADA. I thought it was for signalling and train control.

Traffic diversion on 100-Feet Rd

Chennai: The stretch of 100 Feet Road from Pallava Hospital to PTC Point will be closed for 10 days. Traffic is being diverted to carry out Metro Rail work near Ashok Pillar. The following are the traffic modifications on 100 Feet Road and 2nd Avenue Junction.
All vehicles moving towards Ashok Pillar from 100-feet Road and 2nd Avenue Junction should turn left at 100-feet Road and 3rd Avenue Junction near Pallava Hospital and then take a right turn at 3rd Avenue and 4th Avenue Junctions and proceed towards Ashok Pillar.
The entire 3rd Avenue will be one-way for ten days from Sunday with entry from 3rd Avenue towards 4th Avenue and no entry from 4th Avenue to 3rd Avenue. Vehicles from 4th Avenue and 7th Avenue should proceed towards R-3 Ashok Nagar police station and take a left turn and proceed towards 100 Feet Road via 2nd Avenue. TNN

Finally, they've started tackling the difficult stretches on the route.

In this stretch before Ashok Pillar, the rail goes from the median of the 100 feet road to the left side of the road (on the acquired properties of Jawahar Vidyalaya school and the park), takes a right turn and crosses the 100 feet road diagonally into thr police training quarters on the opposite side.

If they're going to complete this in 10 days, it'll be an achievement. The Pillars on the sides of the road have not taken shape yet.
The stretch in Yellow is the part thats going to be taken up over next 10 days.

I think the deviation on yellow line is for turning radius..

The deviation on the blue line is to avoid disturbing the middle of the road, as that portion is meant for one way traffic.

The yellow part is where the road has been closed for the next 10 days and work is going on.

In view of the Chennai Metro Rail project’s pier & segment casting work on Anna Salai in front of Dr MGR University, Guindy, the stretch of Anna Salai from the university entry gate up to exit gate will be closed for traffic temporarily from Tuesday. To ensure free flow of traffic, all vehicles going from SP Road (Halda) towards Guindy bridge will take the new developed road on the university campus and join Anna Salai near MRC Service Road.


Source: The Times of India, Chennai edition, dated 02-Aug-2011

This is a small stretch just before the guindy bridge. I guess, this is to help metro cross over from median to the side of the road in order to go to the race course side and cross the sub-urban tracks.


Other updates:
- Pillar skeletons have come up for 2 pillars over the adayar river near Kasi theatre. Casting for pouring concrete is being built
- Deep foundation for another pillar, right in the middle of the river seems to be almost complete
- Piling for one more pillar going on.
- The gantry crane is being built on a pillar just outside Kasi theatre. I think this will go towards Udayam theatre / Ashok Pillar as the pillars on the other direction (across river) will take some more time to be completed.

^^They're building pillars in the middle of the Adyar on both lines like the MRTS ???
Couldn't they try a cable bridge design?

In this case, this will just be a bridge across the river. So, this will not affect that much as against MRTS going parallel to buckingham canal and taking up most of the canal space.

Yes.. The elevated highways being built will take care of raping the rivers, not the metro..

Traffic (going towards airport) in front of Spic building has been diverted via Dr.MGR Medical University premises from 11.45 AM today.

Metro Rail to build flyover at Vadapalani
V Ayyappan | TNN

http://epaper.timesofindia.com/Repository/getimage.dll?path=TOICH/2010/02/16/2/Img/Pc0021100.jpg

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.

^^ Ooh, okay, thanks a lot bro.
How far is the station from this junction ???

^^ It looks like the station is a part of the integrated flyover structure - along with parking and access ramps.

Article from today's TOI
Work On Koyambedu-St Thomas Mount Stretch Is Progressing Fast, Set To Meet 2013 Deadline
V Ayyappan | TNN

Metro Rail is on track to meet its 2013 deadline to run trains between Koyambedu and St Thomas Mount along an elevated line. With works progressing at a rapid pace, the Chennai Metro Rail Corporation will begin to lay tracks in the section from January 2012.

Elevated viaducts have been placed over pillars for about 1.5km from Koyambedu on the Koyambedu-St Thomas Mount stretch. Works are on to build the elevated viaducts for the rest of the section.

Koyambedu to St Thomas Mount stretch is part of the 22-km Chennai Central-St Thomas Mount line (Corridor-II). After installing viaducts, firming up the surface on top of the viaducts, laying of tracks and construction of stations, Metro Rail will run trial services from Koyambedu to St Thomas Mount by 2013-end.

The track laying is taken up as a joint venture by Larsen and Toubro (L&T), Alstom Transport, SA and Alstom Project India at a cost of 449.23 crore. Track laying will start from Koyambedu. “The tracks are going to be imported,” said Metro Rail general manager (public relations) S Krishnamoorthy.

The tracks will be of standard gauge (4 feet and 8.5 inches) which has a low turning radius. This has been used for metro rail networks in several world cities like Cairo, Madrid, Bangkok, Manila and Beijing. “Standard gauge is preferred because most of the metro’s components are imported. Manufacturers across the world build machines, coaches and engines on standard gauge. It’s easier to source track laying equipment and rolling stock of global standard if the gauge we follow is the same as the one used worldwide. Metro Rail will be able to get the best companies to build its infrastructure,” a senior official said.

The Koyambedu-Ashok Nagar stretch will be completed first because the contract to install the elevated viaduct was awarded to Soma Constructions as early as in February 2009. L&T, which won the contract to build the elevated viaduct from Ashok Nagar to St Thomas Mount in January 2010 have also started a good portion of the works.

On the same corridor, the stretch from Chennai Central to Koyambedu is underground. Preliminary works like soil testing have started along Poonamallee High Road under which tunnels will run till they reach Aminjikarai. Soil tests have been completed near Chennai Central.

“Soil tests are essential to finalise the design of tunnels and underground stations,” said a Metro Rail official. Metro Rail is planning to start boring works by year-end when tunnel boring machines would arrive from abroad.

Two Metro Lines

Corridor I: Washermenpet to Chennai airport (via Anna Salai)
Corridor II: Chennai Central station to St Thomas Mount (via Koyambedu)


PROGRESS SO FAR:

1) Chennai Central to Saidapet (underground) stretch of Corridor I:
Soil tests began two months ago. Tunnel boring machines will be employed to avoid digging out earth for the underground construction. This work is expected to begin in December.

2) Saidapet to Officers Training Academy stretch of Corridor I:
Pile work has been completed and pillars are being erected. Viaducts will be installed near Officers Training Academy soon. Work on metro station at Guindy has begun.

3) Chennai Central to Koyambedu (underground) stretch of Corridor II:
Soil tests were carried out in June at Chennai Central and Egmore

4) Koyambedu-St Thomas Mount stretch of Corridor II:
Tracks will be laid first in this section. Work is set to begin near Kathipara flyover and at Kasi theatre

http://epaper.timesofindia.com/Repository/getimage.dll?path=TOICH/2011/08/03/2/Img/Pc0020800.jpg
FAST FORWARD: The Koyambedu-Ashok Nagar stretch, complete with elevated viaducts, is expected to be finished first

Moving Ahead One Step At A Time

STAGE 1
Soil test
Around 75 boreholes were used to test soil condition at various places. This was to find whether underground rail or elevated corridor was best suited in that location. This began in 2003
STAGE 2
Pile load test
Earth was bored for 27 metres near Koyambedu and close to 10 metres in other areas to gauge how much weight the earth could withstand. Load tests were carried out in 2009-2010
STAGE 3
Building piles and pillars
Underground piles were built to provide support to overhead pillars of the elevated corridor. After that, pillars were built near Koyambedu bus terminus, Arumbakkam and Vadapalani by mid 2010
STAGE 4
Installing viaducts
After pillars were built, huge prefabricated viaducts were installed using cranes on top of the pillars. Viaducts have been installed on a 1.5km stretch from Koyambedu
STAGE 5
Laying tracks
After the base structures are built, standard gauge rail tracks will be laid. The track will require minimal or no maintenance. Metro Rail plans to begin laying of tracks from Jan 2012
STAGE 6
Building stations and depot
Koyambedu to St Thomas Mount stretch will have seven stations. This work will start at a later stage because entry and exit ramps have to be set up at all stations

449.23 cr is the cost of laying tracks. This project is a joint venture of Larsen and Toubro, Alstom Transport, SA and Alstom Project India

In my experience of dealing with India's suburban trains I have observed that the overhead transmission lines vibrate badly when a train passes through very fast. As a result, sparks fly off and land by the side of the train. Several years ago, some sparks almost fell on me when I was walking along the narrow express train platform at Mambalam station :ohno:. Those sparks are of white in color and that indicates very high temperature. Because of this they will visible only during night time.

Now with the Metro going to have that overhead transmission, what are the design aspects to prevent these sparks from flying off and landing on someone's head below? :nuts:

Tomorrow we will come to know the fate of this project speed! Funds allocation may appear in budget.

It is heart warming to note that 2013 deadline will be met. Taking the cue fro Banglore & Delhi Metro it will be at least make a start in mid 2014. Connecting Central & Koyambedu in 2015 should be real milestone. Five years from now we should see a new city well connected. Even that thought gives a lot of happiness. Let's see what happens on the Mono.

Now with the Metro going to have that overhead transmission, what are the design aspects to prevent these sparks from flying off and landing on someone's head below? :nuts:

IMO metro trains wont be traveling at that high speed [since the avg distance between the 2 stops will be 1-1.5 km] to produce such sparks

^^ I sincerely hope it does not go the way of the Paei Bungalows on OMR - Indira Nagar and Tiruvanmiyur.
There is nothing there of this type.
Or am I missing something ?

^^ He is referring to the Indira Nagar and Thiruvanmiyur MRTS Stations, they are definitely haunted. :-)

Come on. Everywhere in the world, metro and other railways use overhead transmission whether the corridor is at grade, elevated or underground.

It is working elsewhere because they have suspended the wires with the right amount tension and spaced them accordingly to avoid vibration. I hope they do the same here tool.

Come on! You think we Indians won't do it?

@chennai indian:

Though I am not very clear about the situation in which you were in, It seems a normal situation.

When ever there is a jump from one cable to another, there will be air gaps in between and sparks might come. It generally occurs at joints or line change areas.(technical name, I do not know)

they have started constructing D-wall near thiru-vi-ka park and they blocked roads nearby

It is working elsewhere because they have suspended the wires with the right amount tension and spaced them accordingly to avoid vibration. I hope they do the same here tool.

Don't worry as long as IR is not handling the project :)

Viaduct has almost reached SAF Games Junction in Koyambedu (just 1 or 2 pillars short).

Work is going on in full swing to finish the ashok nagar end of soma. they have blocked the stretch of 100 ft road from Pallava Hospital to the Hot Chips junction for 10 days. Ideally viaduct by soma in that region should be completed by then.

As far as the Vadapalani double decker flyover with metro and station on top is concerned, the pillar skeletons have sprung up in the entire stretch and scaffolding work is on to cast the first pillar in this stretch. That was some really visible quick work in the last few days.

90% of pillars completed inside CMBT campus.

Ashok nagar station in the police ground is shaping up well. lots of pillars have sprung up inside the campus.

90% pillars have been completed around udhayam theatre and RTO.

Assembly of a new gantry crane (L&T's third on this same stretch) has begun in front of Kasi Theatre. (WOW L&T rocks)

CMRL finally gets some circular pillars across the Adyar river in jafferkhanpet. the circular pillar skeletons have sprung up there as well.

The viaduct has reached virtusa building on one end.

wide pillars for SIPCOT station in front of Hilton are almost done.

Has any renders for the stations been released?? Ideally, shouldn't we be seeing atleast a few renders by now??

^^ Renders were released for Airport and St. Thomas Mount stations. I don't know if they will be followed, though.

^^

Yes, it is surprising that no official renders have been released. I smell something fishy here!!!! Hope the stations turn out good.

Ok hold on.

I forgot this.

If you read again, I wrote metro and other railways.

I was not saying every single metro or railways uses OHE but in every part of the world, you can see trains (metro or inter-city) running on OHE whether it's Europe, Asia, Africa, Australia or Americas.

OHE is by far more common than 3rd rail (which is mostly limited to metros).

Btw where is mannadi ... And whether it is in metro line ..??

Mannadi is in North Chennai. It will have a metro station between High Court and Washermanpet Stations.

When I saw the construction of pillars first time, I was wondering what was the pipe in the middle of each pillar meant for. Few day back I happened to see that it exits at the bottom of the pillar and it appears to be the drain for the viaduct.
Is my interpretation correct?

Possible, because I have seen similar pipes in Delhi also.

The 100 feet road project has topped P/92. In a couple of weeks will cross the SAARC Games village gate. At this rate it may even touch the CMBT in a months time.

I am posting the debate about this issue from railway forum:

The petitioner wants to know the height of the elevated part and distance between twon pillars... it should not affect the car pulling of Vengishwarar and also Vadapalani murugan temple which cuts the IRR. Here is the car pulling route:

http://i55.tinypic.com/5bw4xu.jpg

And i wonder when the pillars are going to fall on the median, will there me any more land needed for the project? TOI's article is not clear on this... And still they have not yet decided the height of the elevated part above the present Vadapalani signal and distance b/w two pillars?

The temples looks to be 800years old and belongs to Chola Empire with the Tamil inscriptions found in temple.

Enna Arul?? Vadapalani Murugan koil car pulling route nu sollitu Korean padatha pottu irukeenga! :lol::lol:

Hi All. Its nice to see the plans for Stations coming up. But... By any stretch of imagination it would take atleast a year to 1.5 yrs to build a station as said in the plans. I'm not sure if this is on & there is any news on this. We always see the talks on Piers and viaducts, Nothing much to talk about stations which i'm sure will stall traffic on the roads for a considerable amt of time. Especially the vadapalani station which is a 2 tier station... Worrying!!!

^^ Station work is in progress near Hilton Hotel.

Have they placed the order for TBMs? when are they arriving and how many are going to be deployed at a time.

In Bangalore media (and the namma metro thread), I keep seeing such detailed coverage of arrival, assembly and digging progress of the 2 TBMs there. The machines have also been given some names (Helen and something else)

But here in Chennai, all preparations going on for UG stretch. but no news of the TBMs yet. Similarly, there are no station renders also, clear official coach design (we've been gathering coach images from newsletters, alstom website etc. But no final official render).

It'll be nice to get some info on these.

But the physical progress seems very encouraging.

Hi Vijay. As of now on the UG section, soil tests are going at full speed on most of the locations as you'd be aware of... Once thats thru (in another 3 months i guess) we will have TBM's by the year end and start underground metro by Dec-Jan... So we will also have a lot of progress on UG side sometime next year onwards!!! :)

for the 28 km underground section i think they will get a minimum of 6-8 TBMs.....otherwise itl take a long time to complete the UG section

Rather more than that. In Delhi, 14 TBMs were simultaneously used for 31 km u/g sections of Phase-II.

In CMRL's site at Vadapalani (in front of HDFC Bank building), they have started fixing the side pavements on top of the viaduct. The first piece has been fixed yesterday. Will try to get a pic of it soon (or if anyone else can it before i can - you are MOST WELCOME :) ).

Also, some yellow metal works have been installed on top of the viaduct near Lakshman Shruthi Musicals. Have no idea what they are for.

Seems like CMRL is steadily marching on towards completion. :cheers:

Cool! Hope they start laying the tracks soon.

are the side barriers the same design as that of DM and NM??

When I saw the construction of pillars first time, I was wondering what was the pipe in the middle of each pillar meant for. Few day back I happened to see that it exits at the bottom of the pillar and it appears to be the drain for the viaduct.
Is my interpretation correct?
Yes sir it is.
You will notice at the bottom, it'll be L shaped and will pour out onto the road. ..

^^
Cool.. Thx.:)

Hi friends,

is there any video which can show us how the viaduct is installed between two pillors. I would like to see that how it is being done..

Sethu

Found this in Youtube, guess its a recent video

1 pillar has been prepared for filling cement

Soma has commenced parapet wall construction near SRM university . The wall is curved and looks like the one in Bangalore metro

The second gantry crane has reached pillar 92 . After this they will be slow as the metro has to move away from GST into CMBT . The pillar similar to a football goal post has to be constructed to support the segments and only the side pillars has been completed

All pillars inside CMBT has been completed .

Someone please update on the underground Work of Chennai metro.

I feel Chennai metro should be extended to Sri preumbadur and one line connecting Redhills and Chennai Central running Via Madhavaram, Kolathur Perambur purasai, Vepery, Periamet along the 242 route.

Also more metro to connect Sub urbs in North and west Chennai as they are short of reliable MTC or Suburban service.

^^

Thanks Arun. Thats a huge update.. :cheers:

Me too, I didn't understand.
I'm trying to think of a curved wall along NM.

Very Good arun, appreciated for the details. It's like a mini CMRL Newsletter.

Update

The second gantry crane has reached pillar 92 .

Thanks Arun. Nice updates. Btw, where exactly is pillar 92? Is this the last pillar on 100 ft road? Or is it opposite SAF entrance?

What are they doing to the dismantled Ashok Nagar gantry crane? Have they installed it in CMBT?

What is the status of St.Thomas Mount station? Has CCCL started the preliminary works?

^^ These pillars are very low?

^^ They cross flightpath. So CMRL reduced the height

^^ So in future, there is no chance of running a double-decker bus through this route :ohno:

^^ Why not?? there is enough clearance for that still!

^^ So in future, there is no chance of running a double-decker bus through this route :ohno:

The distance between planes and the elevated line will be atleast 70m. Any aircraft in normal condition is 30m above the runway threshold(piano keys).

Wow - really tall pillar - guess this must be near Vadapalani?

Thanks Arun. Nice updates. Btw, where exactly is pillar 92? Is this the last pillar on 100 ft road? Or is it opposite SAF entrance?

What are they doing to the dismantled Ashok Nagar gantry crane? Have they installed it in CMBT?

What is the status of St.Thomas Mount station? Has CCCL started the preliminary works?

Pillar 92 is opposite SAF entrance

They have brought huge cranes to dismantle the gantry crane

I saw some iron rods sticking out. Dunno the progress they have been barricaded more than 8 feet tall.

Superb updates, Mr. Madras!! Thanks! :)



Wow - really tall pillar - guess this must be near Vadapalani?

Yes this is near Lakshman Sruthi Signal

great work!! Thanks..

^^ They cross flightpath. So CMRL reduced the height

No as these are station pillars . They will be low to accomodate the first floor of the station and the platform will be in the second floor. Please check the SIDCO station . It is also similar.

MTC does not have any intention to run Duble decker becos Chennai roads have trees on both sides and running double decker will need axing of these trees, They have tough time running A18 tambaram-broadway . These buses brush the trees along the way.

Nice update Arun and Mr.Madras


Piling in the stretch between AL HQ and Chinna malai has made good progress

Iron rods for 4 pillars has emerged in the chinna malai junction and 7-8 pillars inside the Adyar river



This portion of Anna salai is just 4-lane! Initially I thought pillars will two sides and the station will be in the middle right above the Anna salai! But now with pillars are raising even in this part, I wonder how traffic will be managed here! The vehicles crisscross here...

1. SP road-Anna Salai traffic towards Saidapet
2. Guindy side Anna Salai traffic towards SP road..

It will be night mare after metro completion with pillars in the center of the road.

Metro was progressing very well but my concern is on vadapalani flyover cum station completion on time since about 75 percent critical work pending.

Multi-agency, multi-modal transport study launched

: The Chennai Metro Rail Limited (CMRL) has launched a study to identify where metro corridors can integrate with existing public transit facilities.

The study, ‘Issues involved in multi-modal integration in Chennai', is being carried out with the participation of Chennai Corporation, Chennai Metropolitan Development Authority and other agencies. The results will be ready in six months. The data collected will be used to devise long-term strategies for smooth transfer from one mode of transport to other after major projects such as Metro Rail, Bus Rapid Transit System and Monorail become operational, in addition to existing modes, according to senior officials.

The study will also be a stepping stone towards having a unified ticketing system for all modes of public transport.The Chennai Corporation is likely to make a survey of the bus route roads in proximity to key areas of multi-modal integration such as Egmore, Koyambedu and St. Thomas Mount. Proposal for feeder services would be made based on the survey. The likely shift in the pattern of bus transport necessitated by major public transport projects such as Metro Rail and Monorail would also be analysed. The Metropolitan Transport Corporation will carry out rationalisation of routes based on the results. The number of spots where bus bays, parking lots and regulation of hawkers are required would be calculated.

The need for pavements, signage, walkthrough and pedestrian interchanges for seamless transfer across different modes would also be studied. The study would suggest best practices that can be internalised by various departments.

It would provide a framework for implementation of projects in the long term for optimum multi-modal integration by each of the agencies.

I dream of a metro map similar to this one for Chennai

^^

that is serving the Beijing muncipality which as a pop of about 1.9crores.. almost double the size of Chennai. Only Delhi will have such dense metro competing with Beijing and Shanghai metro... I don't think Chennai needs such a vast metro density.

I dream of a metro map similar to this one for Chennai

http://www.bjsubway.com/templates/images/pic_dtyyxlt.jpg

would have been the most suitable model if they made a proper full fledged metro like this for chennai.

^^ I guess CMRL will get to this point sometime later around 2030 and it takes time. 2/3 lines of 70 km every 5/6 years will be great. :) I hope CMRL prepares DPR for the Phase II meanwhile. :| [Dream eh?]

Chennai won't need such an extensive network, especially if SR and MRTS are revamped. Besides with a proposed Mono, it will be ... you know ... types.
As for Double deckers, is MTC running articulated buses ???

Chennai would need such extensive network in a couple of decades. Slow n steadily we can get there by 2030-35. Lets see how mono gets going. Can't tell anything now.

Yea, MTC is running articulated buses

I dream of a metro map similar to this one for Chennai
...

Vendaanga, onnum puriyala :lol: Idhu jilebi ezhutha vida kashtama iruku :lol:

BTW, the loops in the Beijing subway map remind me of the Chicago loop.

^^ While just dreaming, why not dream for something like this? :)
All of this built before 1940 !!! I've always been amazed at the density of the route construction. The core part - Manhattan is accessible from every corner of the city.

And this is the subway for the core city alone.
Apart from this -
>> there is Long Island rail road to long island which are extended NY suburbs to the right of this map.
>> Metro North going to suburbs in the north of this map
>> NJ Transit lines going to NY suburbs in the New Jersey Area beyond the left of this map
>> PATH rail system catering to immediate areas of Jersey City and Newark to the left of the map

On top of this, there are numerous bus routes, ferries etc. No wonder NY is the only city in US where more than 50% of ppl do not even have a car. (this is a standout in a country otherwise addicted to cars)

Of course, despite this, the core city is always choked with traffic. When around 19 million people + millions of tourists converge on a narrow island - it is bound to happen

MRTS lessons worth learning

Chennai Metro Rail would be in a unique position to try many innovative experiments to revamp the face of public transport in the city, say experts. Photo: M. Vedhan


The Mass Rapid Transit System (MRTS) corridor has been in existence for over a decade. The 25-km line, which was originally supposed to be Chennai's ‘Metro', continues to be plagued with problems. It transports less than 20 per cent of the projected passenger capacity.

Though the elevated rail line, which was a unique experiment, has been a failure on many counts, it offers important lessons to upcoming public transport systems such as Metro Rail and Monorail, say experts.

Even Chennai Metro Rail Limited's (CMRL) initiation of a multi-modal integration study last week is borne out of the city's experience with MRTS and its lack of connectivity.

K. Rajaraman, Managing Director, CMRL, said: “Physical infrastructure such as ramps that connect upcoming Metro stations with nearby bus stops, skywalks heading into suburban railway stations and pedestrian walkways would be in place by the end of 2015. The study will also have a strong focus on pedestrian facilities.”

But similar promises were made back in 2007 when the MRTS extension from Mylapore to Velachery became operational. Metropolitan Transport Corporation buses were supposed to come inside MRTS stations and pick up passengers. The inability to keep this promise has had a telling impact on passenger patronage.

Though there are 21 MRTS stations, only three account for 40 per cent of the total passenger boarding and alighting. These three stations – Beach, Mylapore and Velachery – have a bus stop very close by.

“These are significant transfer points. It is true that inter-modal transfer is not happening in any other station,” said S.Anantharaman, Chennai Divisional Railway Manager, Southern Railway. “We do raise such issues during coordination meetings, but MTC is grappling with its own problems. The hope is once the metro becomes operational, such transfers will become significant and there will be greater incentive for coordination,” he added.

A senior CMDA official said that other measures that were proposed to be introduced on the MRTS corridor but never took off are shuttle services in the vicinity of the station, privatising maintenance operation as well as the functioning of lifts and escalators, and free passes for school students. The metro would be in a unique position to try such experiments, he said.

Other market building measures such as leasing space in stations for public events and branding exercises that would result in social acceptance for a new public transport mode are also required, he added. For example, the Ahmedabad BRT was operated as a free service for the first three months.

K.P. Subramanian, former professor, Urban Engineering Department, Anna University, said that one disadvantage the metro would face is it will be operating on already over-saturated roads.

“Buses will operate parallel to the metro corridor. There was better scope for coordination and integration with MRTS where buses could have operated on routes perpendicular to the rail line.”

He added that the success of Metro Rail's efforts to achieve multi-modal integration will be a test case for the relevance of the Chennai Unified Metropolitan Transport Authority (CUMTA). Though the authority was set up last year, not even a single meeting has been conducted till now.

“The fact that CUMTA's board is packed with government officials, without any representation from NGOs and academics, is a major drawback. Only if the authority can wield enough influence among various public transit operators will the people's interest prevail over the profit or loss of an individual organisation.”

I don't understand why coordination must wait for the metro to be operational. You need to plan now so that you are ready when the Metro is ready. Secondly, what other incentive did MTC need when the MRTS was completed in 2007?

It is under preparation.

Also depends on the ruling party at that time. :nuts:

They are using that to postpone the 'coordination' thing.

^^ MTC is bus-starved. They have only 3000 buses in operation.

So, What is the deal with that gap between two pillars (I believe the pillars are 119 and 199A or something):?

To meet the growing demands of travellers and to cap the inadequacies of the current infrastructure, Chennai’s Mass Rapid Transit System should become functional at the earliest, insists a report submitted by the Associated Chambers of Commerce and Industry of India (ASSOCHAM)

The apex industrial chamber cautioned that infrastructure in Chennai would be inadequate to bear the projected population of 1.1 crore by 2030, as compared to the present headcount of 89 lakh. “The transportation infrastructure in Chennai is dismal, as buses and trains are acutely overcrowded and sorely lack in comfort and convenience for commuters,” it said.

The study, ‘Urbanising India and Mega Metro Network: Vision for the Emerging Cities of India 2030’, advised that the `14,000-crore metro rail project, envisaging a 45-km public transport system with elevated and underground sections, should be put on the fast track.

Across the country, the number of cities with over 10 lakh people will increase from 48 to 68 in the next two decades, according to the ASSOCHAM study. The number of cities with a population of 40 lakh and above will increase from seven to 13 in the next two decades. The subsequent growth explosion in these cities will account for almost 70 per cent of India’s GDP.

It said implementation of the metro network in Delhi had led to multiple benefits. “Fuel savings due to the Delhi Metro Rail could notch up to `8,000 crore in 2011-12 and rise progressively to `15,000 crore by 2020,” said the study. “Over two lakh officegoers and others travel back and forth via metro, and use their cars to move from home to station and back on weekdays.”

The Delhi Metro has also become world’s first railway project to receive valuable carbon credits for regenerative braking and the environmental technology has also contributed over `2 crore under a United Nations-backed initiative to combat climate change.

About 80,731 four-wheelers and 4.8 lakh two-wheelers on roads have been reduced and the number of buses has dropped by 4,767 because of it. By 2015-16, the reduction in number of four-wheelers and two-wheelers is projected to reach 2.4 lakh and 1.5 lakh, respectively.

Likewise, 12,388 buses will be withdrawn by then, according to a projection by the the ASSOCHAM.

Not even a single tender awarded after february 2011? :ohno:

bcoz there is no more tender to award :lol: (only OTA to airport is left)

^^ only that tender is pending? and its been pending for ages. With JJ not interested in it, am a bit worried about it not getting any attention.

Its due to that airport problem. I think they havent conclusively decided how they are going to take it to the airport. There was a breakthrough a few months back but i beleive it is muddled again. Not sure whats happening.

A small request: I know you guys love mother-tongue so much, but since this thread is on the national/international forum, can you guys write in both Tamil and English ? Cheers :cheers:

Whats going on near ashok pillar hot chips junction ? Any visual update ?

If i remember correctly the stretch is blocked only for ten days or so .. Will they be able to build pillar and attach segments within this short time .. ?
I dont understand.. someone please explain :)

The road is still blocked. For the past 2 days, I'm seeing very less activity in the blocked stretch. There are 2 huge piling machines. I don't see any new pillars there. They are piling just before the Jawahar vidyalaya school.

The statue of George Frederick Samuel, also known as Lord Ripon, was shifted from the lawns of Ripon Buildings on Saturday as part of preparations for constructing an underground Metro Rail station.

The headquarters of Chennai Corporation was named after Lord Ripon, who was viceroy of India between 1880 and1884. In the coming days, the Chennai Metro Rail Ltd will also shift the statue of S Sathyamurthy, mayor of Chennai between 1939 and 1940. The bust of P M Sivagnana Mudaliar, commissioner of Corporation of Madras between 1894 and 1919, will also be relocated to enable the tunneling work.

"The statues will be kept on the northern side of the campus and shifted back immediately after construction is completed," a senior CMRL officer said. Ripon Building will celebrate its centenary year in 2013.

A structure built on the southern side of the building to mark the golden jubilee of India's independence and inaugurated by late Union minister Murasoli Maran will also be removed soon. After requests from Akila India Devangar Samooga Nala Sangam, the civic body has asked CMRL to spare the statue of former mayor Pitty Theagaraya Chetty, located in front of Ripon Buildings.

Nearly 50 staff members of Pachaiyappa's College observed a hunger strike here on Saturday against the proposed acquisition of 3.5 acres within the campus for the Chennai Metro Rail project.

S. Murugesan, a botany professor and one of the protesters, alleged that the acquisition would affect the quality of life of students. “The main entrance is planned to be taken over. Hundreds of trees will be cut during the construction. Despite initial promises about the acquisition being temporary, we recently got orders from the Directorate of Collegiate Education to permanently hand over the land. This is unacceptable,” he said.
Alternative entrance to hospital

At the Kilpauk Medical College Hospital on the same road, an alternative route has been planned to enter the premises as the main entrance will soon be taken over by the Metro Rail project. “The alternative way to enter the premises will now go past the boy's hostel, the mortuary and will lead to the labour ward,” said Dean S.Geeta Lakshmi.

With space on and near the median to be utilised for the project, vehicles using the stretch would be pushed to the corners, just a few metres from the hospital building. Therefore, the hospital authorities have requested the Chennai Metro Rail Ltd. to instal a barricade lining the building so that privacy of the hospital is maintained.

As some of the patients have expressed concern about the impact of the drilling work, the hospital has written to the CMRL about safety issues, Medical Superintendent of the hospital R. Sukumar said.

A police station, post office, an outpatient counter, an inpatient registration wing and waiting rooms for staff have already been demolished in the KMC for the Metro Rail work.

“However, we have ensured the new block that has started functioning on the premises has a casualty and outpatient wing all under one roof so people do not have to cross over to access services at the college,” said Mr.Sukumar. Sub-Inspector of Police M.Parasuraman said previously the public could access the police station as it was near the casualty block. “As many burn victims come here, we are required to be available at all times. Now, when the ambulance comes in, we have to walk across and make enquiries.”

GREAT!!! The only pending tender. Link (http://chennaimetrorail.gov.in/tenderaward.php)

Viaducts, Ramps and Cut - Cover Tunnel between OTA Station and Chennai Airport Station

So its going underground?

^^ Yes, it will be underground for a short distance between OTA and Meenambakkam stations (near the secondary runway). Here are the details.


As far as the descent to underground, here is what I gathered from CMRL's newly released alignment:

Right after leaving OTA station the descent starts.
For the next 450m the viaduct pillars will be lowered gradually and after crossing the NH (from median to the OTA side), there will be a ramp for 240m as it enters the airport premises.
Then a gradual descent below the ground level for 340m.
The underground section which is at the most 9m below the ground level runs for 500m and then comes back up (another 180m ascent to reach the ground level).
From there another 140m ramp and gradually increasing viaduct pillars for 295m before it reaches the Meenambakkam station.

So in total 930m for descent and 615m for the ascent to the viaduct level.
The difference between the descent and ascent is because the 500m underground is at a slight elevation (it starts at 9 m and ends at 7m).

There doesn't seem to be any change after the Meenambakkam station.

Nice. Any idea about Lanco? Have they done any metro work in other cities? How are they?

why it should go to underground? that 500m cannot be in ground level by demolishing few buildings in other side of the GST?

why it should go to underground? that 500m cannot be in ground level by demolishing few buildings in other side of the GST?

The whole point is to bring the metro as close to the airport as possible. They are planning seamless integration oof metro with the airport lounge by walkalators. There is a video in MAA thread posted a few days back. You can see that.

As per AAIs request, the stretch where the planes cross the Metro line (inside AAI boundary) it will be underground. But it will be done by Open Cut Method (and not tunnelling)

Then again at elevated level at the Thirisulam airport.

Meenambakkam station under Lanco's scope. Airport terminus under CCCl's scope. OTA station under L&T's scope.

No Metro .. But they are into a range of engineering works.

Some structures of underground stations found ‘dangerously close' to heritage buildings

: A subcommittee of the Heritage Conservation Committee constituted by the Chennai Metropolitan Development Authority has raised concern about the adverse impact the proposed Chennai Metro Rail stations would make on heritage buildings. The subcommittee found some of the structures of the proposed underground Metro stations such as the vents and entrance porches to be `visually intrusive' and ‘dangerously close' to the heritage buildings. “While there is scope to aesthetically merge a few structures with the adjoining heritage buildings, some should be relocated and kept away,” one of the members of the subcommittee remarked.

Recently, designs for underground metro rail stations near High Court, Central Station and Mannadi were reviewed.

In the proposed High Court metro rail station, as the design drawing indicates, one of the vent structures and entrances is located about 2 meters from the Dr.Ambedkar Government Law College, a heritage building which is more than 100 years old. These structures rise about 5 meters above ground and were found to obstruct the view and affect the heritage building. Similarly, in the case of the proposed metro rail station near Central Railway station, vent and entrance structures were found to be visually dominating the Ripon building and Victoria Public Hall.

Another member of the heritage subcommittee pointed out that the station near Mannadi may not seriously impact the Tamil Wesley Church, a heritage structure nearby. However, suggestions to modify other stations have been made to Chennai Metro Rail and their response is awaited, he said. Detailed drawings and studies of visual and urban impact of metro rail stations on heritage areas have also been requested for evaluation.

When contacted, S.Krishnamoorthy, Chief General Manager (Public Relations), Chennai Metro Rail limited (CMRL) told The Hindu that the Heritage Conservation subcommittee has made some suggestions.

“The CMRL is working out the technical drawings based on the suggestions and when the drawings are completed, they will be submitted to the heritage committee for their perusal and approval,” he added.

Two Metro Rail corridors totalling to a length of about 45 km has been proposed at the cost of Rs. 4,000 crore. Work is under way in both the corridors: Washermenpet to Airport and Chennai Central to St. Thomas Mount.

Eleven underground and six elevated stations are to be built on the Washermenpet-Airport Corridor, and eight underground and seven elevated stations are to be built on Chennai Central-St.Thomas Mount Corridor.

The project is expected to be completed by 2015.

They decided to go underground (of course cut and cover), to avoid the obstruction to the secondary runway approach path. I don't think going at ground level on the other side would be a viable solution.

The whole point is to bring the metro as close to the airport as possible. They are planning seamless integration oof metro with the airport lounge by walkalators. There is a video in MAA thread posted a few days back. You can see that.
I don't think this going underground has anything to do with bringing metro as close to the airport as possible. This underground stretch is only between OTA and Meenambakkam. The line is elevated when it goes near the airport terminals.

I think his question was why is it not taken to the other side of GST (meaning to the east side where suburban line runs adjacent to GST). His doubt was why so much effort in building the line to the west (on the side of airport) of GST.

Expansion of Metro Rail

.......

Chennai Metro Rail Ltd. (CMRL) have reported that they have awarded contracts for various equipments except lifts and air-conditioning of underground stations to Consortia of international company with Indian firms. Thus, part quantity of the coaches and critical equipments for signaling, telecom, platform screen doors, tracks, automatic fare collection, overhead equipments and Supervisory Control And Data Acquisition (SCADA) are being imported by these contractors. As far as rolling stock is concerned, CMRL’s contractor has planned to import only nine trains and the rest is proposed to be manufactured in India.

What does that have to do with expansion? These news people have some random title just for the sake of having them.... :ohno:

Guys, the corridors for the initial 111 kms of the monorail have been announced. And as i posted in the monorail thread, i feel that selection of corridors have been good so far as they mainly concentrate on transporting the public from the outskirts / suburbs to the core city. If the remaining part (189 kms) of the monorail also concentrate on this purpose by plying on omr, ecr, nh4, nh5, bypass etc..... then the transportation within the city will be served best by metro in the future.

i know i have high hopes..... but i really do hope that better sense prevails for the future monorail corridors as in this case.... so that there is scope of expansion of metro in the future ( whether the government changes or not). :smug:

What is your opinion on the corridors???

That news had content from Delhi, Bangalore, Mumbai metros too and talked about expansion in those.. I edited them and have posted only relevant content related to Chennai. Please click the link and go through the article fully to find out why they have kept that title

Good to know our stations will have platform screen doors..

Last of Metro Rail contracts awarded
A Channel Will Keep Line Below Surface Near Airport

Chennai: The Metro Rail’s airport corridor is finally taking shape. Haryana-based Lanco Infratech has bagged the Rs 178.94-crore contract to build the 4.3km corridor from the Officer’s Training Academy (OTA) to the airport.

With this, all contracts for construction of Metro Rail have been awarded. Two corridors -- from Washermanpet to airport via Anna Salai and Chennai Central to St Thomas Mount via 100 Feet Road – have been planned.

There was a delay in awarding the contract for the airport corridor because the Airports Authority of India (AAI) and airlines said the line would affect flight safety because it runs under the flight approach path to the secondary runway.

“We have decided to build a box-type channel to keep the line under the surface for 500m. The trains will run below the surface so that flight safety is not affected,” said a senior Metro Rail official. The change in design is expected to cost an additional Rs 50 crore.

The line will enter the airport campus as soon as it leaves OTA station and dip to go underground at the GST road end of the secondary runway. It will climb to reach the level of the elevated Meenambakkam Metro station that will be constructed in the middle of GST road.

Metro has told the contractor to build two 380m-long ramps – one to take the line underground from OTA station and another to take the line above ground to reach Meenambakkam station.

“We will also build a 260m inverted U-shaped covering at the point where the line enters the tunnel. The tunnel will not be as deep as the tunnels planned for underground stretches of the metro line,” he said.

The original plan was to construct the line at an elevation of 25m. This was revised to 6.5m of which 3.5m would be above ground as the line passed under the flight path.

However, Metro Rail and airport officials held a meeting and inspected the spot after air safety experts pointed out that the line would be a safety hazard.

^^ I guess this is the last contract from CMRL, not necessarily last contract for the Metro rail work.

What about the Airport Metro station. I don't see any tenders for this yet? Will AAI construct it by themselves?

The only information I could find about the Airport Metro station is this: (Sorry if this was already posted, but my search couldn't find this in previous posts).
