History

These locomotives were built by a consortium of Mitsubishi, Hitachi and Toshiba (The Japanese Group, as attested by a plaque fixed on their sides) as a second option to the Europeans WAG-1. They were delivered in 1960 and were a bit lower powered than the WAM1 but had similar Bo-Bo wheel arrangement (4 wheels per bogie) with four Hitachi DC traction motors connected to the wheels permanently in parallel through a WN geared drive. The WAG-2 had Ignitron rectifiers just like the WAG-1 but some were later were refitted with Excitron rectifiers. Some even had the Mitsubishi logo painted on their sides. These have not been retrofitted with air train brakes. Like the WAG-1 they were also used around the ER-SER-NER-NR circuit as it was the first AC electrified area and hauled ordinary passenger trains and freights only. They were also used double-headed for freight trains. They had Four traction motors permanently coupled in parallel are fed by ignitron rectifiers. Speed control is by a tap changer on the input transformer. Mitsubishi transformer, 20 taps. Oerlikon exhauster and compressor, Arno rotary converter. They were homed at Asansol Loco Shed of Eastern Railways and then transferred to Bhusawal and Itarsi sheds of CR in 1985.Due to aging these locomotives were withdrawn in 2001.None have been preserved
