Ahmedabad likely to get a new-look, but slower metro

Gujarat government has fallen back on the experience of Delhi Metro Rail Corporation (DMRC) while preparing a new Detailed Project Report (DPR) which suggests a new-look metro for the Ahmedabad city that will be longer and slower, than the earlier proposed versions.

“DMRC has executed the new DPR,” said Vijay Nehra, Chief Executive Officer (CEO) of MEGA (Metro-Link Express For Gandhinagar & Ahmedabad), a special purpose vehicle formed for the implementation of the metro project in two cities of Gujarat.

DMRC had first prepared and submitted a detailed DPR for the Ahmedabad metro project in 2004, when Gujarat Infrastructure Development Board (GIDB) had engaged the corporation for creating a regional rail system that was expected to be commissioned by 2010.

“We decided on DMRC because it has successfully implemented the Delhi metro and has also hand-held similar metro projects in other cities,” Nehra added.

Lacunas in the earlier DPRs and absence of a general consultant for the project are being seen as major reasons behind creation of a new DPR.

This new DPR – prepared by the DMRC – has been cleared by the MEGA board and submitted to the Gujarat Government for approval. The first phase of the project costing Rs 10, 675 crore will be commissioned in 2018 and aims to carry 4.6 lakh passengers daily.

Unlike the earlier DPR that was prepared in 2012 when ex-IAS officer Sanjay Gupta was at the helm of MEGA, the new DPR proposes that the metro will move on a rail corridor with a standard gauge (1435 mm), instead of a broad gauge (1676 mm).

The new DPR also proposes the tried and tested 750V DC third rail electric traction, instead of the 1500V DC traction proposed in the earlier DPR. “This change was effected, because there is no metro in India that currently runs on 1500V DC traction,” Nehra said, adding that tried-and-tested versions of metros in India have been kept in mind while suggesting a new metro for the cities in Gujarat.

Compared to the earlier provision of two cars per train (during non-peak hours), the new DPR proposes a longer metro train with three cars, each having a capacity to carry more than 450 passengers. This would mean that one metro train will carry almost 1400 passengers at a time, compared to the earlier 800.

As per the new DPR, size of the Ahmedabad metro coaches will be 2.90 meter, smaller than the 3.2-3.6 meter wide coaches proposed in the earlier DPR prepared in 2012.

The “driverless” Ahmedabad metro will have a “scheduled speed” of 30 kmph, compared to the 45 kmph proposed earlier. The number of maintenance depots have also been reduced to two (New Cotton Mill for East-west corridor) and Vasna (North-South Corridor) as compared to the earlier four depots.

The East-West Corridor (Thaltej Gam to Vastral Gam) that will have a total length of 20.5 kms, will have 6.3 kms of underground route and will cost Rs 6681 crore while the North-South route (APMC-Motera Stadium) that will comprise 15.5 kilometers of elevated corridor, will cost almost continued…
