The model name stands for broad gauge (W), AC Current (A), Mixed traffic (M) locomotive, 1st generation (1). They entered service in 1960, thus making them the first AC electric locomotives to be in service in India. A total of 100 WAM-1s were built by the European consortium between 1959 and 1961, which made them the most numerous class of mainline electric locomotive until the WAG-1.
The Indian locomotive class WDS-6 is a diesel–electric locomotive used by the Indian Railways mainly for shunting and also for performing departmental duties. The model name stands for broad gauge (W), Diesel (D), Shunting (S) engine, 6th generation (6). As of April 2022, 375 units of this class are currently in use all over India.
Diesel Loco Shed, Tondiarpet is a motive power depot performing locomotive maintenance and repair facility for diesel locomotives of the Indian Railways. It is located near Tondiarpet railway station (TNP) of the Southern Railway zone in the city of Chennai, Tamil Nadu and is one of the four diesel loco sheds of the Southern Railway, the others being at Ernakulam (ERS) at Kochi, Erode (ED) and Golden Rock (GOC) at Trichy.

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.
The WDM-2G is a class of diesel electric genset locomotive used in Indian Railways. It is one of the rarest locomotives in India with only two units being produced by Patiala Locomotive Works (PLW). The locomotives were produced with an intention of being fuel efficient and to be used for light to medium duties such as short passenger runs along with occasional shunting. They are one of the only two classes of locomotives in India to feature multiple prime movers, the other example being WDS-6G, which was designed solely for shunting. They have a rated power of 2,400 HP.

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 class WDS-3 was a diesel-hydraulic locomotive used by Indian Railways for shunting and doing departmental work. The model name stands for broad gauge (W), diesel (D), shunting (S) 3rd generation (3). The WDS-3 is used mostly in the Northern Railway Zone (NR).

The model name stands for broad gauge (W), Diesel (D), Shunting (S) 1st generation (1). The WDS-1 is used mostly in the Northern Railway Zone (NR). All these locomotive s were withdrawn from service by the late 1990s.
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 stands 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.
