There were also a few hydraulic diesel shunters in use at Integral Coach Factory, Diesel Locomotive Works and Chittaranjan Locomotive Works. These were rated at 250 hp.[10]

Note: There is no electric shunting engine in India. Classes from WDS 1 to WDS 4D have hydraulic transmission. The WDS 4, 4B, 4C and 4D are the only still existing broad gauge locomotives with diesel-hydraulic transmission.

Converted locomotives
WCDS6 is a converted YDM4 locomotive into a broad gauge locomotive. This rebuilding was carried out by the Golden Rock shed. It was built for large industrial concerns. The first one was delivered to RITES. Rest being same, new water and air lines are added. They also have a modified control stand and dual brake system. Also, they have Broad Gauge bogies and under-frames.

Diesel multiple units
A few routes in India currently have Diesel multiple unit service. Depending on the transmission system they are classified as DEMU (diesel-electric transmission) or DHMU (diesel-hydraulic transmission). There are diesel railcar service in a few places known as 'railbus'.

These are among the earliest electric locos used in India. The first locomotive was named as Sir Leslie Wilson and is currently preserved in the National Rail Museum, New Delhi. 2600–2950 hp)
WCG 2 (Designed by Chittaranjan locomotive works in 1970. 57 built until 1977. 4200 hp. Max speed 90kmph.[11] 35600kgf tractive effort. Were used extensively around the year 2000 when Mumbai was out of traction power. Out of service[12])
Electric multiple units
WCU 1 to WCU 15 (Used in Mumbai region only)
AC electric traction
The 25 kV AC system with overhead lines is used throughout the rest of the country.
