The Delhi Metro has been active in escort in a new era in the sphere of mass urban transportation in India. The system introduced comfortable, air conditioned and eco-friendly services for the first time in India and completely revolutionized the mass transportation scenario not only in the National Capital Region but in India.

Special Features in New Metro Trains

The Delhi Metro Rail Corporation (DMRC), which has ordered 131 new trains because of the increased rush on the Metro system in Delhi, provides passengers with power connections inside the coaches so that one can use laptops and charge mobiles while 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 compact noise levels inside the trains as the DMRC is making key design changes to lessen the noise levels by using special sound absorbing cushions in the walls of the Metro coaches and more buffing on the Metro doors which will be better sealed by dropping the door gaps to ensure that less sound from outside enters the trains thus allow the passengers to travel in a better feel.

The noise level in the underground coaches is 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 are used in the air conditioners of the Phase-II coaches which is sealed and is more compact and this will reduce noise level in the coaches further.

The Phase-II Metro coaches also provide a much better level of passenger comfort as for the first time there is 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 is maintained at 25 degree Celsius and relative humidity is 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, 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 behaviour in every part of the train at all times.

The trains in Phase - II are also being designed to travel up to 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 porous couplers which can absorb shock and reduce damage to the car body structure in collisions.
