After 41 years, WCG 2 was introduced to India. They were completely built in India. By the late 1960s with the WCG1s were getting a bit long in the tooth and the newly introduced WCMs performing poorly on freight duties in the ghats prompted CR to look for a dedicated-freight successor to the Crocodiles. A decade of R&D and testing resulted in the mighty WCG2, when rolled out (1970) was the heaviest (132t), most powerful and the locomotive with the highest tractive effort (35.6 tonnes) in India. The WCG2 was designed and developed completely in India by RDSO and built at CLW. However, they were not really completely indigenous but were a mix of features taken from many successful locomotive designs, featuring technological cues borrowed from some Japanese locomotives of the time. In the year of 1970, 57 units were produced. They had a top rated speed of 80 kmph
