The Indian locomotive class WAG-1 was a class of 25 kVACelectric locomotives that was imported from Europe in the 1960s for Indian Railways. The model name stands for broad gauge (W), AC Current (A), Goods traffic (G) locomotive, 1st generation (1). A total of 112 WAG-1 were built by The European Group 50 Hz Group/European Group/50 Cycles Group (consortium) between 1963 and 1966. They entered service in 1964.[1]
The WAG-1 served both passenger and freight trains for nearly forty years. As of January 2002, all locomotives have been withdrawn from service, with one being preserved at the National Rail Museum.
Forty-two locomotives of this type were ordered from European Group. Five of these were completely assembled in Europe and the remaining were built at CLW. A repeat order was placed on for 20 locomotives in 1963. Further these locomotives were manufactured at CLW. The typical feature of these locomotive is the Monomotor bogies. This construction results in substantial saving in weight in traction equipment and gives better adhesion. The traction motors are force ventilated and are fully suspended type. These motors are permanently grouped in parallel and are controlled by tap changer and field weakening. This can be used for a multiple unit operation to a maximum of four locomotives. Compressed air brake for the loco and vacuum brake for the train are provided, in addition, these locomotives have been provided with regenerative braking. Few locomotives have been converted to dual brake system. They were in service until 2002 when all but one were scrapped. The first indigenously CLW produced WAG-1 20710 'Bidhan' is preserved at the National Rail Museum, New Delhi.[2]
