The million dollar question troubling thousands of commuters waiting for the completion of Metro lines: When will we be able to travel in Metro from one corner of Bengaluru to another?

Bangalore Metro Rail Corporation Limited (BMRCL) had earlier given the deadline of February for the inauguration. However, February came and went without seeing the real inauguration of the project, though the work has been happening slowly.

Decoding the Metro test terms

Once the tracks, stations, electrification and signalling systems for Metro are ready, there are many tests to be conducted, to ensure the safety and reliability of systems. Oscillation trial is one such important test. Trains tend to oscillate, or shake at high speeds, which could be violent and can damage track and wheels, and even cause derailment. This problem needs to be addressed in the track design, by adding a differential that accounts for this. There is a tolerance limit of oscillation for every track, and the oscillation should not cross that limit.
Oscillation trial checks whether the train is running precisely on the track and looks for any movement away from the track. It assesses how the train is swaying when it moves, and which speed is safer for the train to run. Railway Design and Standards Organisation (RDSO), Lucknow, conducts this for all Metro tracks in India. Process of passing this test can take maximum 10 days, in the absence of major glitches.After oscillation trials, emergency braking system, controllability and fire safety systems are tested, in order to check the response in emergency situations. After this, the certificates issued assure that the tracks are fit to host running trains. Metro applies for CMRS inspection post this. CMRS authorities conduct inspection and issue the required certificates and authorise Metro to open the corridor. Any non-completion of work, or any technical, engineering or unanticipated glitch in any stage of certification will need to be rectified, and this leads to delays.Procedure for certification of Metro trains is explained in this file. This flowchart shows the various stages involved and timeframes.

This line will enable people to travel from Mysore Road area to M G Road to Byappanahalli in Metro. With proper feeder buses, reaching different areas in Whitefield will be super easy. However it will take at least one more month to open the lines for the Metro train.

Though the work has almost been completed, a Times of India report said that the CMRS survey is yet to be commissioned. Pradeep Singh Kharola was quoted as saying “We’ve completed the oscillation trials which are the most crucial part of getting ready. The stations are complete and getting the final touches. We are waiting for a speed test certificate by the Railway Standard and Designs Operation (RDSO) in a week’s time, which is the first step to begin the process of seeking clearance, followed by a Schedule of Dimensions (SoD) and a few more certificates expected to be issued by the first week of March.” He added that these tests were needed to be done before the BMRCL approaches the Commissioner of Metro Rail Safety (CMRS) for the certification process.

Travel from Nayandahalli to Baiyappanahalli this April onwards

The East-West corridor or Purple Line as it is known in Metro lingo, covers a distance of 18.10 kms. In this, two reaches (Reach 1 and 1a, and Reach 2 and 2a) are already open, and cover MG Road to Baiyappanahalli and Magadi Road to Mysore Road.

There are four stations that are yet to be commissioned: Cubbon Park (Cricket stadium), Vidhana Soudha, Central College and Majestic.

According to the February newsletter released by Bangalore Metro Rail Corporation Limited (BMRCL), civil works for the Cubbon Park station have been completed. All entry-exit structures are completed except the one on North-West side. Architectural finishing works and final finishing works like false ceiling and painting are being done. Escalators from ground to lobby to platform level have been installed and commissioned. Lifts are installed. Track-linking for East and Westbound tracks has been completed. Oscillation trials have been conducted from East Ramp to West Ramp.

Next station is Vidhana Soudha Station. Here civil works have been completed. Architectural finishing works are almost complete, and finishing works like false ceiling and painting are being done. Road above the station has been restored and  is open to traffic. Escalators from concourse to Platform and Ground to concourse have been installed and commissioned. Lifts have been installed.

Sir M Visvesvaraya Station (Central College) is the next, where the civil work and entry-exit structures are completed. Escalators and lifts are installed and commissioned. Architectural finishing works and final finishing works are in final stage of completion.

The biggest and most important intersection in the loop is Bangalore City Station. Here civil works of the station and all the four entry-exit structures have been completed. Architectural finishing works are in advance stage of completion. Final finishing works like false ceiling & painting works are being carried out. Escalators have been installed.

Metro Newsletter says that fire safety inspection for Sir M Visvesvaraya Station (Central College) station is pending, while all other stations have undergone the inspection. Upon getting fire clearance, BMRCL will invite the Commissioner or Metro Rail Safety to conduct the final inspection and initiate final certification process.

Realistically, this stretch of Metro can be fully operational in April, or maximum May 2016.

North-south corridor (Nagasandra-Puttenahalli): A few more miles to go!

This is also called Green Line, and covers a distance of 24.20 kms. The North leg (Reach 3, 3a, 3b) of the project is open connecting the Sampige Road (Swastik) to Peenya Industry and Nagasandra.

There are three tunnel boring machines (TBMs) working underground to complete the north-south line. Underground tracks are not laid in one tunnel but there will be two tunnels for to-and-fro movement.

One tunnel coming from Majestic to Swastik Metro station, coming out near Krishna Floor Mill, having a distance of 955 metres, got completed in November 2015 with the help of Margarita Tunnel Boring Machine.

According to a BMRCL newsletter released on March 8, Godavari Tunnel Boring Machine tunnelling the North tunnel between North Ramp (Krishna Floor Mill) and Majestic Station completed 747 metres in February, with 226 metres remaining out of 973 metres. In January, Godavari completed a distance of 687 metres. the progress for February being 60 metres.

Another pending underground stretch is between Chickpet to Majestic. Krishna TBM boring the northbound tunnel between Chickpet (South ramp) and Majestic stations completed 273 metres, while 474 metres were remaining out of 747 metres, as on March 8, 2016.  In January, Krishna had completed 78 metres according to the newsletter published in February. Total progress was 195 metres in February 2016.

Kaveri Tunnel Boring Machine tunnelling the southbound tunnel between Chickpet and Majestic Station completed 593 metres, with a balance of 154 metres out of 747 metres. Completion of this tunnel is crucial for Metro to start the oscillation trials and other tests in the Metro stretch between National College and Puttenahalli. Kaveri completed 575 metres in January, thus the progress in February is just 18 metres.

On Reach-4 (Krishna Rajendra Market-Rashtriya Vidyalaya Road)-South Corridor (4.10 kms), 99% of work is completed in K R Road, Lalbagh and South End Circle and Jayanagar stations. 98% of work is completed in R V Road Station. Overall progress completed is 99% at all the stations, says BMRCL newsletter for March 2016.

On Reach-4a (Rashtriya Vidyalaya Road- Puttenahalli Cross) South Extension Corridor (3.90 kms), 98% of work is completed in Banashankari, 99 % of work is completed in Jaya Prakash Nagar and Puttenahalli Cross. Overall work progress at all stations together is 98%.

Why is the North-South stretch being delayed?

Right now the BMRCL is unable to commission the compulsory tests on the south leg of the North-South corridor connecting KR Market and Puttenahalli. The trains on this stretch need to have a depot where they can be serviced regularly, which is impossible now because there is no track yet to connect the trains to the south leg and the depots. As of now there are two depots, one at Peenya and another at Baiyappanahalli.

Tunnel boring work takes a lot of time, as Bengaluru sits on a rock, and the tunnels will go up to 22 metres beneath the ground. In the Majestic intersection, the East-West line will be on the top layer 8-9 metres below the ground level, while the North-South one will be at a lower level, at 21.14 metres according to the DPR of Phase-I of Namma Metro. In reality the the lower level goes upto 22-23 meters.

Hence it will take many more months to finish the tunnelling, station clearances and tests done in the North-South line.However Metro officials are hopeful of completing the North-South line as soon as possible.

BMRCL hopes to complete Phase-I by December

In a press interaction that took place on March 15, 2016, Pradeep Singh Kharola, Managing Director of BMRCL, said that the BMRCL aims to start commercial operations from Sampige Road to Majestic interchange by June-July 2016, thus completing the northern reach of the Metro, which will enable travel from Nagasandra to Mysore Road and Baiyapanahalli.

On March 15, work was on in war footing in level 1 (East-West line) on Majestic interchange. The North-South line that passes through the lower level in the interchange has been isolated from level 1 to enable smooth work on the East-West station.

Kharola added that by August 2016, the BMRCL wants to open Puttenahalli to National College line. By December commercial operations of North-South Metro will start. Thus the new deadline for north-south corridor, and Phase-I, set by BMRCL is December 2016 before which BMRCL wants to complete all the works and commission trains.

    Namma Metro Status Report.

    When a City reaches a population of 3 million, it is not possible to meet the mass transportation requirement by bus transport. A Rapid Rail Transit System is required. But, in Bengaluru, even after reaching eleven million population, Metro Rail network is not ready except two small stretches and commuters are forced to use their own vehicles. At present, the number of vehicles is 6 million creating acute traffic congestion, long journey time, slow speed, frustration, and risk to commuters.

    Government should have entrusted the Metro Rail project on PPP mode to inter-national companies when they approached Government. But, Government has taken up the project under public sector. The result is delay, huge cost of the project, and non-availability of mass transit facility to the large number of commuters. The project will take many more years to complete the network.

    It is suggested to introduce Mono-Rail System on the heavy traffic corridors not covered by the present Metro Rail Project to attract the commuters to mass transportation. This will curb growth of private vehicles.

    Dear Doctor,

    Why do urban planners and experts like you want complicated glass and concrete solutions like Monorail and Metro?

    I am a layman but I am aware of the fact that Suburban rail’s ridership shall be 25 lakhs and costs Rs. 8500 crores for a 440 KM network Compare this to Metro, which cost us Rs. 13000 crores for just phase one of 42 kms.

    Do we need to talk about Monorail after the grand failure of Monorail in Mumbai? I don’t want to speak about elevated rail lines like MRTS of Chennai.

What is the ‘smartness’ quotient of Chennai?

The Smart City Advisory Forum was convened in Chennai only 5 times since 2016, showing minimal participation by elected representatives.

Chennai is among the first few cities to get selected under the Smart City Mission programme in 2016. As many as 48 projects under different categories were taken up under the scheme. With only a couple of projects left to be completed, isn't Chennai supposed to look 'smart' now? The much-hyped Central government scheme, launched in 2014, was envisioned to build core infrastructure and evolve 'smart' solutions that would make cities more livable and sustainable.

Scenes from a community walk in Mumbai

When I moved to Mumbai, the city felt extremely 'walkable,' but a walking tour in Dadar broadened my definition of walkability.

When I moved to Mumbai in June 2023 for work, I found myself going for sight seeing to the city's tourist destinations. Though the city appeared to have consistent and wide footpaths almost everywhere, vehicular right of way seemed to be prioritised over the pedestrian right of way. This struck me as very strange, even as I continued to enjoy walking through lanes of Mumbai very much. On one hand, there is excellent footpath coverage, utilised by large crowds everywhere. On the other hand, speeding vehicles create obstacles for something as simple as crossing the road.  "Though Mumbai appeared to…
