History edit

The history of WCM-6 begins in the early 1960s with the stated aim of the Indian Railways (IR) to remove the aging fleet of WCM class locomotives working in the Central Railways (CR).[1] So IR to procure 2 1500 V DC electric locomotives from Chittaranjan Locomotive Works (CLW), who also previously supplied the WCM-5 class. They had the High Adhesion Bogies used in the WAG-7 class AC locomotive.

They are manufactured in India in 1995. They were the first “non nosed” DC locomotives to be manufactured.[2]

WCM-6 class DC locomotives of Kalyan shed and were converted to work on 25KV AC by Electric Locomotives Works -Bhusuwal on 28 August 2008. The WCM-6 locomotives were used in Freight Duties.
