Indian locomotive class WCP-3

The Indian locomotive class WCP-3 is a class of 1.5 kV DC electric locomotives that was developed in late 1920s by Hawthorn Leslie for Indian Railways. The model name stands for broad gauge (W), Direct Current (C), Passenger traffic (P) engine, 3rd generation (3). They entered service in 1930. A single WCP-3 was built at England between 1928 and 1929.

The WCP-1 served both passenger trains for over 40 years. With the introduction of more modern types of locomotives and 25 KV AC electrification, all were withdrawn by early 1960s. Today the locomotive is scrapped.

history

The electrification of the GIPR began in 1922. Powerful locomotives were required to transport the express trains on the mountain railway to overcome the Western Ghats. They also had to be able to reach speeds of 85 miles an hour (137 km / h)[2] - a very high speed at that time, which was not even the case with the E 501 and 502 of the Paris-Orleans Railway had been requested.[3] Three test locomotives were therefore ordered from different manufacturers in order to be able to select a suitable design for the series. The tender and evaluation was monitored by the UK electrical engineering firm Merz & McLellan in London.

GIPR ordered the following test locomotives in 1923

Specification

The locomotive has three individually driven axles and two two-axle bogies. The axes were driven by a hollow shaft drive from GEC. Technically, it should have some similarities with No. 13 of the North Eastern Railway (NER), otherwise little is known about this locomotive.

gollark: Please cease "OS" production.
gollark: Please don't.
gollark: I can help with webdesigny stuff somewhat.
gollark: Most commonly used programming languages are pretty similar conceptually and you just need to be good at the basic skills of translating what you mean into simple steps computers can actually run.
gollark: Although I'm imagining that many programs would run background tasks then totally fail to cleanup them.
