Today is the day when steam engines took a back seat on India's first railway with railway electrification from Chhatrapati Shivaji Maharaj Terminus (the then Victoria Terminus) to Kalyan commissioned on 12 November 1928 with 1500-volt DC traction system. Electrification was subsequently extended up to Igatpuri in Northeast line and up to Pune in Southeast line.

First passenger train Deccan Queen, with electric loco WCP-1 ran on June 1, 1930, between Bombay VT (now CSMT) and Poona (now Pune).
