Salient features of Rolling Stock Metro

Metros around the world are there to give comfort to the commuter and at a price which is easy on the pocket. India's millions and the especially the denizens of Hyderabad will be in for this experience in a few years from today. 

The specification for standard gauge rolling stock is based on light weight stainless steel/Aluminum‐ bodied three‐car formations, having a trailer car between two motored driving cars. Internal wide gangways will provide ease of passenger movement and assist load distribution. Trains will be air‐ conditioned throughout with designated space for differently abled persons. LCD screen type route map indicators over all the doors and LCD TVs at suitable locations inside cars shall be provided for infotainment. Safety of commuter and operations is paramount for us and the trains will have foolproof safety features and on‐board fire & smoke detection as well.

These trains will have CCTV cameras in and outside the cars, mobile and laptop charging sockets inside the car, better humidity control, microprocessor‐controlled brakes, secondary air‐suspension for better ride comfort and will be capable of maintaining an average speed of 33 km/h and maximum operating speed of 80 km/h. The trains will be using regenerative electric braking thereby converting the momentum into electrical energy and feeding back to power supply system while braking. As a contribution towards the CDM this will reduce the energy requirement from the grid.

The maximum capacity per three car train will be approximately 965 including longitudinal seating, giving a high proportion of the floor area to standing passengers. Each car will have longitudinal seats for approximately 40 persons./li>

Total 171 cars for 57 Trains will be procured for the first phase of the project. Although with many automated functions, the ATO enabled trains will be under driver control.

Having all salient features which will add to the comfort and safety of the commuter, it is aesthetics combined with comfort and safety which will win the metro‐user and make them addicted. Hyundai Rotem (Korea), were chosen based not only on latest technology and price but also on cost of maintenance, service and availability of spares.. Our endeavor is to have an improvement on the existing Metro‐Rail trains.
