DMRC begins process to buy 500 train coaches
After putting work on its ambitious Phase-III on the fast track, Delhi Metro has floated global tenders to procure nearly 500 train coaches that would have several new features and will be more faster and less noisier than the existing ones.
A tender for design, manufacture, supply, testing, commissioning and training of 486 standard gauge coaches for the Phase-III has been floated by the DMRC recently.
A total of 81 six-coach trains will be assembled from these 486 cars and they will be put on Line 7 ( Mukundpur-Yamuna Vihar) and Line 8 (Janak Puri West-Kalindi Kunj).
Once the trains are assembled, 52 will be for Line 7 and 29 for Line 8. Delhi Metro's Phase-III envisages bringing another 103 km under the Metro map and is expected to be completed by 2016.
The coaches will start arriving from later half of 2014 and will be put in service after commissioning.
The new coaches will have several new features both in its interior and exterior from the aesthetic as well as from the points of view of commuters.
"There will be a change in the look of the front cab of the trains which will have a glass on the front emergency door to give it a better look," DMRC spokesman Anuj Dayal said.
He said new trains will have an initial acceleration of 1.2 m/s2 as compared to existing 0.82m/s2 which will reduce journey time and increase the average speed.
Another special feature of the new trains would be that they will be more silent and interior noise level will be further optimised.
Dayal said the new trains will be "highly energy efficient" and shall feedback more than 70 per cent of its consumed energy back to the system during braking.
The new trains will also have energy-efficient LED based lighting, while the rolling stock used currently has fluorescent lighting.
