The Indian locomotive class WDS-8 was a class of diesel–electric locomotive that was developed in 1979 by the Chittaranjan Locomotive Works for Indian Railways, but ended up being delivered exclusively to the private sector. The model name stood for broad gauge (W), Diesel (D), Shunter (S) engine, 8th generation (8). They entered service in 1979. A total of five WDS-8 locomotives was built at Chittaranjan Locomotive Works (CLW), Chittaranjan between 1979 and 1982.

All WDS-8 units were sold to the Steel Authority of India. As of November 2020, these locomotives have been withdrawn from service.

History The history of the WDS-8 class began in the early 1970s with the Railway Board's dual aims of addressing the shortcomings of the preceding WDS-4, and to remove all of Indian Railways' steam locomotives from operational service by a target date of 1990. The WDS-8 was a competing bid from CLW to the Banaras Locomotive Works's WDS-6 class, intended for industrial concerns in the private sector as well as for the Railways itself. The WDS-8 had a MAK diesel engine with a maximum output of 800 hp, which was similar to the engine used in the newly upgraded YDM-1 class. They possessed short cabs modeled on those of CLW's electric locomotives with a single long, narrow hood.

which were then transferred to the plants of the Steel Authority of India (SAIL).

As of November 2020, no locomotives of this class are in service.
