The Indian locomotive class WCM-6 is a class of 1.5 kV DC electric locomotives that was developed in 1995 by Chittaranjan Locomotive Works (CLW) for Indian Railways. The model name stands for broad gauge (W), Direct Current (C), Mixed traffic (M) engine, 6th generation (6). They entered service in 1996. A total of 2 WCM-6 locomotives was built at CLW in 1995. Currently they are used on departmental trains and shunting duties.

History

[edit]

The history of WCM-6 begins in the early 1990s with the stated aim of the Indian Railways (IR) to remove the aging fleet of WCM class locomotives working in the Central Railway zone (CR).[1][anachronism][irrelevant citation] So IR to procure two 1,500 V DC electric locomotives from Chittaranjan Locomotive Works (CLW), who also previously supplied the WCM-5 class. They had high adhesion bogies used in the WAG-7 class AC locomotive.[citation needed]

The two WCM-6s were manufactured in India in 1995. Not counting the dual-voltage WCAM/WCAG series, they were one of only two classes of DC locomotives to have a "boxcab" body style, the other being the WCG-2 class of 1970.[2]

On 28 August 2008, both WCM-6s were converted to work on 25 kV AC by the Electric Locomotives Works of Bhusuwal.[citation needed] Both locomotives are based at Kalyan depot, and are in service as of 2023.
