You've heard right. The Saidapet station's box is now a 40 feet deep pool. The status of the tunnels is unknown, but they can easily collapse under the weight of the water. The damage caused can only be assessed when the water is pumped out.

As a user of Kochi airport since it is opening, I was not too much impressed with its aesthetics, though functionally it was optimal. I hope the Kochi metro turns out to be more eye-catching in addition to being functional.

Since they posted the animation of the entire route at the start, I have high expectations. But we have to wait to see the end result and will it be able to keep the time as promised to date for start of operations.

Rohitji,

What is your opinion on smaller cities investing in metro? Do you think it is financially viable for them or can a good metro start growth?

Like the golf -club look and atmosphere there. Lush green all around. Reminds me of Minsk airport on Sundays....................Calm and Quite. 5 passengers, two piolts and two airhostesses. Neat clean fresh empty airport. But those wezre good old Soviet times.

Depends on the size/importance of the city, but generally speaking, building a metro is quite wasteful in smaller cities - example: Vijayawada & Trivandrum where the projects have been approved by the state govt. The systems here won't even be operationally profitable. It would be better if they invest in providing better bus services.

These days building a metro is like vying for the "international airport" status that became a fad in the 2000s. Every town wanted that label.

Bangalore Metro Will Shut Down Purple Line Next Week For Testing
After conducting full length trials from 6-8 am and 8-10 pm between Baiyappanahalli & Mysore Road stations last month, the Bangalore Metro Rail Corp is now ready for more testing! They just announced that starting this Monday (December 7), operations on both Reach 1 (Baiyyappanahalli to MG Road) and Reach 2 (Magadi Road to Mysore Road) will be suspended for a period of 4 days until Thursday (December 10). This is being done in order to conduct more rigorous testing of all components (signalling, electrification, train interaction etc.) of the underground section from Magadi Road to Cubbon Park of the 18.1 km Purple line.

These tests will go on until Thursday (Dec 10) after which commercial operations will resume on Friday with new timings & frequencies as listed below:
Reach 1 – Trains will run from 8 am to 8 pm with a frequency of 10 mins

Would it open so soon? My understanding is that the tunnelling is not complete (even in the Purple line). Looks like even Kochi metro may become operational before Phase 1 of Metro gets completed :P. And I will have to move around covering my head in a dhothi/mundu if that happens ;).

Thats a lot of walk. Better take an auto. I walked from CV Raman Nagar Big Bazaar to Bayapannahalli station and back for almost a month and it was 10 mins+ either ways. Tin Factory is definitely longer. Plus road crossing is an adventure.

If you wish to go to Manyata from Byappanahalli, take the other exit to Byappanahalli Rly Station, follow the road along the Rly line and catch the Manyata bus at the end of flyover. It may be same walk as Byappanahalli to Tin Factory but much safer and quieter..

I think tunnelling is complete in purple line. But green line is awaiting completion of tunneling along one direction. They will shut down metro (temporarily) for safety inspection runs in underground sections of purple line next week.

^ To add to that - tunneling on the Purple line was completed in March 2014! The entire line should be operational in March/April 2016.

Blurb on Mumbai Metro's 33.5km Line 3 from Colaba to SEEPZ:
MMRC officials said there are lengthy procedures to evaluate technical and financial bids, as per the guidelines of Japan International Cooperation Agency, funding 57% of the project. “The procedure we are following require time as there is an appraisal committee, a tender acceptance committee, then it goes to JICA. So we are looking at another month [to award bids],” said Bhide.
The lowest bidders were announced in September btw.

q: what is the distance between those pillars?

I always feel little scary when I see these I-beams on concrete structures. perhaps I am not sure if the strengths are fine just by the pics and positions. just my fear especially when Richter scale shows up.

What was the reason for going with a long span- since it is crossing a road with a median, couldn't they have placed a regular pillar in the middle? What am I missing?

Re: Mass Rapid Transit in India

Posted: 08 Dec 2015 19:43
by Rohit_K
The width of the median isn't that big. If they would have placed a pillar, then it (along with its protective concrete base-example) would have bulged out and eaten into the lanes on either side.

Hmm. This is interesting, what's your take on it?

Metro Tunnels Come to City's Rescue - C Shivakumar, New Indian Express
Had it not been for Chennai Metro Tunnels, the devastation due to the calamitous floods, coupled with heavy downpour, in the city could have been more.

A Chennai Metro Rail official said that as heavy rains lashed the city, Chennai Metro took a decision to open the blocks and let the rain water inside the underground stretch between Anna Flyover and Saidapet. This had brought some relief to the city.

Intensity of the rain was such that the 4 km stretch from Anna Flyover to Saidapet was water logged. “Imagine if the water in the 4 km stretch with two tunnels, which are 6 metre wide, is let out in the city,” he said. It was a wise decision which saved the city from intense flooding, said the official.

But this might not happen during the next monsoon as a protective wall would be built to make it water-proof, he said while pointing out the reliability of Metro Rail service during the rains.

The biggest challenge before Chennai Metro is how to pump out the water. “This could take more than 10 to 15 days. We are using pumps to flush it out as water in Adyar River has receded,” he said. From December 1 to 5, an average of 60,000 people took the service, he said. Metro Rail is planning to start operations quite early in anticipation of the return of people who had fled the city fearing more rains.

The revenue earned during the five days could be more than `1 crore but officials are happy that Chennai Metro had mitigated the sufferings of the people who could not access any other mode of transport to reach Koyambedu bus station.

This is real data on flooding possibilities of the tunnels and in its aftermath how it affects the quality of the tunnels. A stress test of a kind perhaps, even if the decision was involuntary.

Re: Mass Rapid Transit in India

Posted: 09 Dec 2015 08:10
by Rohit_K
I don't buy the official's claim that some blocks (what are those?) were opened. The tunnels were flooded during the rains in November itself as a protective wall around the Saidapet ramp hasn't been built yet. The slums around the Adyar were first submerged and when water levels rose further, water naturally went inside the ramp leading to the tunnels as there was literally nothing to block it.

Re: Mass Rapid Transit in India

Any damage reports from the flooding of the tunnels ?

Plan and prepare for a similar flooding scenario down the road.

Bade - That will only be known once the water is completely pumped out.

News related to TBM Kaveri which is tunneling in B'lore from Chickpet to Majestic:

Bangalore Metro works: 15 buildings marked for evacuation
The Balepet-Majestic underground section will spell a lot more risk for houses as around 15 buildings have been marked for evacuation in the days to come. The Bangalore Metro Rail Corporation Ltd (BMRCL) has already alerted the occupants of the houses who have agreed to evacuate and return later.

BMRCL senior official U A Vasanth Rao told Deccan Herald: “There are 15 more houses marked for evacuation in the rest of the distance between Balepet and Majestic. The BMRCL has already issued evacuation notices to all residents who have agreed to move out till the time the tunnel boring machines pass through. We have told the BBMP to check on the condition of the houses and inform the residents accordingly. The contractors too should check the status of the houses and make alternative arrangements for families to stay. We follow international procedures in such contexts.”
