The Indian locomotive class WCG-2 is a class of 1.5 kV DC electric locomotives that was developed in the late 1960s by Research Design and Standards Organisation (RDSO) and Chittaranjan Locomotive Works (CLW) for Indian Railways. The model name stands for broad gauge (W), DC Current (C), Goods traffic (G) engine, 2nd generation (2). They entered service in February 1971. A total of 57 WCG-2 were built at CLW between 1978 and 1983, which made them the most numerous class of DC electric locomotive.

The WCG-2 is one of the most successful locomotives of Indian Railways having served both passenger and freight trains for over 40 years. They were famously known for doing passenger duties and banking duties in the Bhor and Thull ghats. However, with the advent of new 3-phase locomotives and conversion of Central Railways to 25 kV AC, the aging fleet of WCG-2 locomotives have been fully withdrawn from mainline duties and were rapidly scrapped. Now 2 locomotives have been preserved.
