The stainless-steel-bodied train has wide inter-car gangways to facilitate passenger distribution within the train. It is fitted with electrically-operated sliding doors, air-conditioning, a passenger intercom, LCD information displays and LED destination signs.

The 80km/h train is powered by three-phase insulated-gate bipolar transistor (IGBT) traction equipment produced in India. Regenerative braking should reduce energy consumption by up to 30% compared with existing Kolkata metro trains.

The eight-car train will accommodate up to 3050 passengers. Each train cost Rs 400m ($US 6.2m) to build which ICF claims is half the cost of an imported metro train.

Once testing has been completed, ICF will build 26 1676mm-gauge trains for the Kolkata metro. ICF has also offered to build a prototype train for Chennai Metro Rail as a 1435mm-gauge demonstrator.
