The Indian locomotive class WDS-2 was a class of diesel-electric locomotive that was developed in 1954 by Krauss Maffei for Indian Railways. The model name stands for broad gauge (W), Diesel (D), Shunting locomotive (S) engine, 2nd generation (2). They entered service in 1955. A total of 20 WDS-2 was built in Germany between 1954 and 1955, which made them the most numerous class of shunting diesel locomotive until the WDS-4B.

The WDS-2 served both shunting and departmental trains for over 45 years. As of January 2020, all locomotives have been withdrawn and subsequently scrapped. None of the 30 locomotives have been preserved
