Around this time next year, the city will bid a final goodbye to the last vestiges of the Direct Current power supply that is still in use on the suburban railway network.

The Central Railway (CR), the last zone in Indian Railways to use 1,500-volt Direct Current (DC), will switch over to 25,000-volt Alternating Current (AC) entirely, by June-July next year, making the 90-year-old 1,500-volt DC power system redundant.
