Electric Locomotive --- It was in the 1929, electric traction with 1500V DC was introduced for the first time in India between Bombay and Kurla-a 15 km stretch. The emergence of electric traction was due to difficulty in maintenance of a huge number of steam locomotives in the steep ghat sections of Bhore ghat and Thal Ghat in Great Indian Penninsular Railway for banking and also to avoid scarcity of water in arid regions. In 1928, a 36.21 km stretch between Bombay & Borivili of Bombay, Baroda & Central Indian Railway (BB & CI) was electrified. And by 1929 the entire stretch of 53.1 km from Bombay to Kalyan was electrified. Entire 138 km section between Kalyan & Pune was electrified at one side and 53.2 km stretch between Kalyan & Igatpuri completed electrification on the other side by the end of 1930. On the southern part a meter-gauge line between Madras Beach & Tamabaram was electrified on 1930. And finally in 1936 the 26.22 km stretch between Borivili & Virar was electrified. By the time of Independence, India had total 388 km of electrified lines and it was decided to continue on steam traction, though the Calcutta suburban network was electrified using 3KV DC around 1954. By 1957 it was decided that the network was to be gradually electrified with 25KV AC to be adopted as traction following the recommendation from French National Railway Corporation and 2000 km of route length to be electrified by the next 8 years. On 1st July 1966 along with its 4th definitive series, IndiaPost issued a postage stamp with 0.10 paisa denomination to commemorate the advent of Electric Locomotive era in Indian Railways. The stamp depicts the 1st electric locomotive built by CLW - Lokmanya, a WCM5 class locomotive.
