The Indian locomotive class WAG-4 is a class of 25 kVACelectric locomotives that was manufactured by CLW in late 1960s for Indian Railways. The model name stands for broad gauge (W), AC Current (A), Goods traffic (G) engine, 1st (1). A total of 186 WAG-4 locomotives were built by The European Group 50Hz Group/European Group/50 Cycles Group (consortium) between 1967 and 1969. They entered service in 1967.[1]
The WAG-4 served both passenger and freight trains for over 40 years. As of January 2020, All locomotives have been removed from service all but one were scrapped.
History
The first fifty-six locomotive's equipment were procured from European Group. They had Auxiliary machines and some control equipments have been procured from indigenous sources. All these locomotives were built by CLW. The typical feature of these locomotives is Monomotor Bogie. This construction results in substantial saving in weight in traction equipment and gives better adhesion. These locomotives utilise silicon rectifiers for conversion of ac power into dc. The traction motors are force ventilated and are fully suspended type. These motors are permanently grouped in parallel and speed control is obtained through HT tap changer and TM field weakening.
These locomotives can be used for a multiple unit operation to a maximum of four locomotives with compressed air brake for the loco and vacuum brake for the train are provided. In addition, these locomotives are also provided with rheostatic braking. Few locomotives have been converted to dual brake system later on by Railways.
Specification
Build dates: 1966-71
Wheel arrangement: B-B ( monomotor bogies like WAG 1 )
