Answer 1

Special Features in New Metro Trains

The Delhi Metro Rail Corporation (DMRC), which has ordered 131 new trains in view of the increased rush on the Metro system in Delhi, will provide passengers with power connections inside the coaches so that they can use their laptops and charge their mobiles while they are travelling in the Metro. Every new Metro coach of Phase – II will have power supply points for this purpose.

The Metro coaches in Phase - II will also have reduced noise levels inside the trains as the DMRC is making major design changes to reduce the noise levels by use of special sound absorbing cushions in the walls of the Metro coaches and more buffing on the Metro doors which will be better sealed by reducing the door gaps to ensure that less sound from outside enters the trains thus enabling the passengers to travel in a better ambience. The noise level in the underground coaches has been reduced by 8 decibels(db) as in Phase-I the internal noise levels was around 92 db which will now be only 84 db in Phase-II. In addition, a new type of compressor called Scroll Compressor System will be used in the air conditioners of the Phase-II coaches which will be sealed and is more compact and this will reduce noise level in the coaches further.

The Phase-II Metro coaches will also provide a much better level of passenger comfort as for the first time there will be Humidity control as Humidity Sensors will activate the newly planned heating system of the air conditioner which will eliminate humidity inside the coaches. The temperature will be maintained at 25 degree Celsius and relative humidity will be maintained at 60 % during the summer and monsoon months (in Phase - I trains, there was only temperature control).

With the start of Phase-II the Delhi Metro will start travelling very far distances covering around 50 kms in some destinations such as Dwarka-Noida, Gugaon-Jahangirpuri, etc. To avoid confusion for the passengers who will travel on these lines, there will be new destination sign boards in LED on one window of the side wall of each coach so that passengers can view the terminal stations while standing on the platform as some Trains may be terminating at intermediate stations depending upon operational needs. This will be necessary as on the same line different trains may be terminating at different destinations.

Phase - II trains will also have Closed Circuit Television Cameras (CCTVs) inside the coaches apart from cameras outside the coaches so that the driver can see the entry and exit of passengers from the train. The driver of the Metro trains will now be able to observe passenger behavior in every part of the train at all times.

The trains in Phase - II are also being designed to travel upto a maximum design speed of 95 kmph as against 90 kmph in Phase - I. The braking system is also better as DMRC will use Wheel Mounted Disc Brakes which will be micro processor controlled. In addition, the train will have energy absorbent couplers which can absorb shock and reduce damage to the car body structure in collisions.

Explanation:

Salient features of Delhi Metro.

1. The Magenta line. It's the sixth line on the Delhi Metro that reduces the travel time and an effective cost of commuting.
2. Train control (CBTC). It's the system designed to reduce waiting time from 120 seconds to 90   seconds.
3. The two-seaters- Three and five seaters have replaced them.
4. The poles which have been replaced by three parallel support bars so that more people can hold on without hands overlapping. #answerwithquality & #BAL
