Several MRTS proposals for Bangalore have been in the pipeline for nearly 24 years. In 1982, a study suggested that the MRTS should have a route length of 12.20 km. and pegged the cost at Rs. 239.15 crores.

In 1983, the Metropolitan Transit Project, an organization of Indian Railways, prepared a feasibility report for provision of suburban rail services on existing lines, a circular railway of 57.9 km. metro system on two corridors, in Phase-I 12.9 km. from Rajajinagar to Jayanagar and in Phase - II 11.2 km. from Hudson Circle to Krishnarajapuram. In 1988, a World Bank aided study was carried out by RITES and the study recommended a Commuter Rail System along with improvement of road transport system.

Later, in 1994, the Bangalore Mass Rapid Transit Limited (BMRTL) was incorporated by the State Government to implement the mass rapid transit system. BMRTL in turn asked the IL&FS to carry out a feasibility study for LRT System on Public-Private Partnership. However, though the partner was selected, the project did not take off. Later, Delhi Metro Rail Corporation (DMRC) in partnership with RITES prepared a Detailed Project Report (DPR) for Bangalore Metro Rail, Phase I in 2003 at the instance of the Government. It proposed two double line corridors: East-West (EW) and North-South (NS) with a total length of 33 km.

The Bangalore Metro Rail finally took shape with the Karnataka Government clearing the project in March, 2005 and the Union Government giving its approval in April, 2006.



Phase I
Consists of 42.3 kilometers of route length of which 8.8 kilometers is underground while the rest is elevated



Construction has been divided into 4 elevated 'reaches' and 2 underground sections:

@Akash, why viaduct is in wave shape?
Euro ji,
There is slight variation in the Gradient,but when zoomed through the lens it gets more prominent-Optical illusion I must say.Nandan is right this has been shot from the skywalk-station,with great zoom so the result is wavy...


Example:



The author presents this in his blog article:

The wavy looking tracks denote that the camera was zoomed way way out (photographer talk).I ain't claiming nothing, so hold the phone calls. If it's not the wye, make believe, I do. Life ain't that serious.

Just caught it on tv.... those turnstiles are HORRRRRRIBLE... bright purple and bright green :(:(
BTW, the source of the photos is from within mg road station
They are not turnstiles, they are flap gates.

@Akash, why viaduct is in wave shape?
I know 2 reasons.

One is that the height of viaduct is higher near stations and is lower between stations for gravity reasons. This means a train approaching a station will have to climb up and it's speed will automatically reduce. Hence energy will be saved in braking. Similarly, when train leaves the station, it will climb down and gravity will help in increasing speed, again saving energy.

Second reason is that it is costlier to build taller pillars because of obvious reasons, that's why their height is lower along the viaduct but the station platform needs to be at higher level (+2 level) because it has to accommodate one more floor below it (the concourse level which is +1 level) and the concourse level needs to have enough clearance for vehicles passing under it (ground level). Hence the height of pillars near stations needs to be higher so that viaduct can climb to platform's level.

Tunnelling work yet to gather pace

Work on underground stations progressing well

The underground tunnelling and station construction work on Namma Metro's East-West Corridor appears to be moving at an average pace with the two tunnel boring machines (TBMs) drilling about 300 metres cumulatively so far.

Helen, the TBM launched during the third week of May, commenced its work in the first week of June from the TBM shaft in Majestic. So far, it has burrowed about 240 metres, which must have reached up to Janata Bazaar on Kempe Gowda Road.

On the other hand, Margarita, the other TBM, commenced the work about one-and-a-half months later, has drilled about 40 metres, a BMRCL spokesperson said.

At this speed, Helen might require about six to eight months to reach Sir M. Visvesvaraya (Central College) underground station and Margarita about nine months. At the Bangalore City Station (near Magadi Road), about 90,000 cubic metres soil has been excavated so far after the contractor constructed 432 of the total 444 soldier piles.

At the Visvesvaraya station, 318 of the 367 soldier piles have been erected. Work at the Vidhana Soudha underground station is progressing satisfactorily.

Isn't it optical illusion?/ :dunno: May be you are right...

No. You can see the difference with naked eye from a station platform. Have observed this a lot in Delhi metro. You can actually see train rising upwards while entering the stations and vice versa.

http://www.hindu.com/2010/01/04/images/2010010457490101.jpg
That's because the elevated road is following the road topography. It needs to maintain certain minimum height of clearance and also to ensure that pillars are not too tall (thus increasing the cost). Hence it follows the road. This is different from what I discussed about waviness in metro lines.

In case of metro, if the gradient changes (esp if the change is steep), then they prefer maintaining a constant gradient for the viaduct, so the pillar height varies to maintain constant height of the viaduct over a certain distance (and this is exactly opposite of this image).

At long last, a smooth ride on Metro

A day after Chief Minister D V Sadananda Gowda expected more transparency in the functioning of Namma Metro, Bangalore Metro Rail Corporation Ltd (BMRCL) authorities took journalists to its MG Road station and on a ride to Byappanahalli and back.



Delays and the Metro rail project have been synonymous, but step inside the station or the rakes and they give the impression that workmanship far exceeds the initial operational hiccups that dogged the mass rapid transit project.

Compared to January first week, when Deccan Herald had managed to travel on one of the rakes from Byappanahalli, the trainride on Thursday was faster, smoother and without the hitches –– a reflection of the work that has been achieved in the last seven months.

Not bogged down by glitches through the journey, as was the case during the trial run in January, the train chugged along the “Up” track to Byappanahalli and “Down” to M G Road in less than 30 minutes, at a maximum speed of 75 kmph. This is in sharp contrast to the three-hour one-way journey the Metro team took in January, which eventually saw suspension of trial runs for the next few days.

The swanky interiors of the stations cannot overshadow the BMRCL’s committment to disabled commuters which is evident from the entry gates to the lifts and even the train. At the entry points, the largest gate is reserved for the disabled who will be able to use wheelchairs easily. The buttons on all the lifts are placed low so that physically challenged people can access them with ease.

Besides, they have numbers and letters inscribed in Braille on all for the visually challenged.

As for the coach’s first door, designed for passengers on wheelchairs, a Metro official said: “It is immediately behind the locopilot’s coach so that he is able to help the passenger if required.”

The security system appears equipped to handle emergencies well and also to prevent probable mishaps. Technology, with CCTVs, rear-view display monitors/TVs for drivers, trained security personnel and operations staff will be a first-of-its-kind experience for Bangaloreans.

With clearly marked platforms, pass details, signage and and an effective public announcement system in place, BMRCL is awaiting clearing the last hurdle before it throws open operations on the reach to the public.

Even the coaches have multiple passenger information display systems capable of making announcements in three languages: English, Kannada and Hindi.

BMRCL spokesperson B L Y Chavan said: “We are almost through. We are ready to commercially open it the day after we get the final nod.”

Bengaluru Metro already a terror target

Sources said the terror threat was revealed by officials from the Union Home Ministry who visited the BMRC office recently with the sketches and photographs seized from the terrorists.



The IT capital, rocked by the 2008 serial bomb blasts is under renewed terror threat with the new target being Namma Metro stations on Reach One, scheduled for a grand opening on September 15, which could see Prime Minister Manmohan Singh in possible attendance.

Terror suspects recently detained in Delhi were found with sketches of the metro stations and the city’s major installations, top sources in the state secretariat told Deccan Chronicle.

Sources said the terror threat was revealed by officials from the Union Home Ministry who visited the BMRC office recently with the sketches and photographs seized from the terrorists.

“A team of officers including National Investigation Agency visited the BMRC office on KH Road and showed them the detailed blueprints of the metro stations and the sketches of other vital installations seized from terror suspects, who had been picked up by New Delhi police. The officers asked the BMRC to immediately remove building plans of the stations, detailed route maps, pier and girder details with emergency exit and entry points for moving fire tenders, from the website of the corporation,” he added.

The union home ministry has now passed strictures to all corporations handling public projects not to put out details of the projects on the website, the officer said.

On Thursday, the Bangalore Metro Rail Corporation (BMRCL) took mediapersons to the Mahatma Gandhi station to show its readiness for commercial operations. The good news is, the station appeared to be ready to handle passengers.

However, the BMRCL spokespersons maintained that safety certification was more important for them than dates.

“We are eager to have the safety certification first. We are awaiting the sanction from the railway board to open the line after which we can appeal to the Commissioner of Railway Safety for metro to come and inspect the line,” said BLY Chavan, spokesman of BMRCL.

BMRCL sent an application for sanction to the Commissioner of Railways Safety in Secunderabad and also to the railway board in Delhi last Tuesday.

Meanwhile, chief minister DV Sadananda Gowda said the metro would be inaugurated on September 15. He has already invited prime minister Manmohan Singh to flag off the metro. It is expected that everything will fall in place once the safety inspections are over.

Metro says all the five trains are ready for operations. At the beginning, their frequency will be every 10 to 15 minutes.Depending on the demand from passengers and ridership data, the frequency will be increased to every five minutes.

Metro has more trains to support the operations if the frequency is increased.

A sneak peek into Namma Metro
BANGALORE: The 13 minutes and 16 seconds long ride from MG Road to Byappanahalli is there to enjoy on Namma Metro but without the official stamp on safety.
Giving media persons a sneak-peek into the ride which has not been inaugurated yet, the Bangalore Metro Rail Corporation Limited (BMRCL) explained the facilities available on Reach 1.
Stopping at five stations, the ride helps you travel above one of the most congested parts of the city with a token ticket that costs just `15.
The complete ticketing information has been put up in all stations along with a customer care executive to answer queries.
Like the Delhi Metro, one needs to place the token or smartcard in the card reading area at the entry gate.
Once inside, an escalator or the stairs takes you to the concourse area.
The concourse on the first floor connects you to the platforms above or the plaza.
The MG Road plaza, which will also have ticketing counters, is not ready yet and officials say that the construction will be over only by December.
There are clear signs guiding you to the platform that helps you take the up route (MG Road to Byappanahalli) or the platform for the down route (Byappanahalli to MG Road).
Namma Metro will eventually have 6-car trains but to begin with, 3-car trains will ply carrying about 1,000 people.
The really short metro ride has made provisions for safety that include two emergency button boxes that will switch off the power at the station when pressed or send an immediate signal to the station master.
In case of an emergency between two stations, there is a provision of a ‘walk way’ that helps people get off the train and walk to the next station.
Each station is equipped with a medical kit that includes a stretcher and a wheelchair.
A tactile route has been put in place to guide persons with disability.
There is also a facility of an elevator.
With CCTV cameras monitoring the entire station constantly, the officials believe that there is little room for mischief on the journey.
There are two screens acting as a rear-view mirror for the drivers in order to check the platform before closing and opening the doors of the train.
Commuters are also guided by screens displaying information relayed through real time GPS and continuous announcements during the journey.
On the way back, the black coloured tokens with a builtin- chip for recognition have to be deposited at the exit gate.
This also acts as ticket checker.
