Metro trains to be introduced in Phase-II would be swankier and better equipped.

Apart from extending facilities like charging of laptops and mobiles on board, they will have humidity sensors; will be faster and less noisy; and have improved brake systems.

The facility to charge laptops and mobiles is one feature that is available in very few metro systems across the world and Delhi can look forward to having them next year.

The Delhi Metro Rail Corporation (DMRC) has ordered 131 new trains for Phase-II that are being built in Germany by Bombardier. These new trains are expected to arrive in March 2009.

“The new features are a result of the feedback we have got from our passengers over the last few years. High noise levels inside the moving trains was one of the complaints we received,” said a top DMRC official.

So, the DMRC is using special sound absorbing cushions in the walls of the coaches and more buffing (process of smoothening metals) on doors, which will allow them to be better sealed and reduce door gaps, which in turn will ensure lower noise levels. From 92 decibels in Phase-I trains, the noise level has been brought down to 84 db in Phase-II trains.

A scroll compressor system would be used in the air conditioners to make them compact and reduce noise.

The trains are also being designed to travel faster — 95 kmph — as against 90 kmph in the Phase I trains. “Some stations in Phase-II are at a good distance from each other and here the trains can pick up good speed,” DMRC spokesman Anuj Dayal said.

The humidity sensors will activate heating system of air-conditioners to eliminate humidity inside trains. Phase–I trains only have temperature control.

The trains will also have better brake-systems and energy absorbent couplers, which will absorb shock and reduce damage in collisions.

With the start of Phase-II, the metro would start travelling distances of around 50 kms on some routes like Dwarka-Noida and Gurgaon-Jahangirpuri. To avoid confusion for passengers traveling on these lines, there will be new LED signboards on one window of each coach. Passengers would be able to view terminal stations of trains while on the platform.

The trains would also have CCTV cameras inside and outside the coaches.
