Between 1925 and 1960 all electrified #railway tracks in #India operated on a Direct Current system. The last sections of 1.5 kV DC from Mumbai to Panvel and Thane to Vashi, were upgraded to 25 kV AC in April 2016. Here is a look at the now extinct DC locomotives of India. 
WCP-1/2 ordered by GIPR to a Swiss Locomotive & Machine Works design for operations over the Western Ghats in 1928. 22 Vickers built locos entered service in 1930 and served into the mid-1980s. With a top speed of 137 km/h, the locos offered 15,295 kgf of tractive power.
WCP-3/4 were two locomotives ordered to General Electric Company and Brown, Boveri & Cie. designs for evaluation purposes in 1928. Built by R&W Hawthorn, Leslie & Co. both offered lower tractive effort and speed than the WCP-1 (EA-1). They operated into the late 1960s.
