The Mumbai Metro Rail Corporation (MMRC) celebrated Independence Day by initiating High Voltage Charging (25KV) of the eight coaches of the first prototype train for the Colaba-Bandra-SEEPZ Metro-3 Corridor.

Charging of every train is a daily and never-ending activity and after charging the train at high voltage of 25 KV AC, static functionality tests of all the sub-systems, such as functioning of air-conditioners, communication system including speakers, public address system etc. of the train will be taken up. It is only after successful completion of these tests the train will be ready for the dynamic design proving trials.
