The Indian locomotive class '''WAG-3''' is a class of 25 [[Volt|kV]] [[Alternating current|AC]] [[Electric locomotive|electric locomotives]] that was imported from Europe in 1960s for [[Indian Railways]]. The model name stands for [[5 ft 6 in gauge railway|broad gauge (W)]], AC Current (A), Goods traffic (G) engine, 3rd (3). A total of 10 WAG-3 locomotives were built by The European Group 50Hz Group/European Group/50 Cycles Group (consortium) in 1965. They entered service in 1965.<ref>https://www.irfca.org/faq/faq-specs.html#WAP-1 &#x5B;IRFCA&#x5D; Indian Railways FAQ: Diesel and Electric Locomotive Specifications</ref><br />
<br />
The WAG-3 served mainly freight trains for over 35 years. As of January 2020, All locomotives have been removed from service all were scrapped.<br />
<br />
== History ==<br />
Ten locomotives of this type were ordered from European Group. All these locomotives have been assembled in Europe. First locomotive was put in service in July, 1965. The typical feature of these locomotives is a Monomotor bogie. This construction results in substantial saving in weight in traction equipment and gives better adhesion. These locomotives utilize 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 controlled by tap changer and field weakening. The traction motors for the WAG3 were two units of Alstom MG1580A1 which output 23% more top power than the WAG1. 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 rheostatic braking.[[Indian locomotive class WAG-4|WAG-4]] is based on this class.<br />
