The Indian locomotive class WCP-1 is a class of 1.5 kV DC electric locomotives that was developed in late 1920s by Swiss Locomotive and Machine Works (SLM) for Indian Railways. The model name stands for broad gauge (W), Direct Current (C), Passenger traffic (P) engine, 1st generation (1). They entered service in 1930. A total of 22 WCP-1s were built in England between 1928 and 1929.

The WCP-1 served passenger trains for over 50 years. With the introduction of more modern types of locomotives and 25 kV AC electrification, all were withdrawn by early 1980s. Today only one locomotive is preserved with the remainder of the units scrapped.

History

The electrification of the Great Indian Peninsula Railway 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) [1] - 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. [2] 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.

The Great Indian Peninsula Railway ordered the test locomotives in 1923

Indian Railways operates India's railway system and comes under the purview of the Ministry of Railways of Government of India. As of 2023, it maintains over 108,706 km (67,547 mi) of tracks and operates over 13,000 trains daily with a fleet of 14,800 locomotives. The railways primarily operates a fleet of electric and diesel locomotives along with a few compressed natural gas (CNG) locomotives. Steam locomotives are operated on mountain railways and on heritage trains.

The Buchli drive is a transmission system used in electric locomotives. It was named after its inventor, Swiss engineer Jakob Buchli. The drive is a fully spring-loaded drive, in which each floating axle has an individual motor, that is placed in the spring mounted locomotive frame. The weight of the driving motors is completely disconnected from the driving wheels, which are exposed to movement of the rails.

The BTB E2E, also known as F 2/2 and De 2/2, were a pair of Swiss electric locomotives operated by Burgdorf Thun Bahn (BTB) in the early twentieth century. They are the oldest three phase locomotives designed for full service operation that have been preserved. The locomotives were built by Brown, Boveri & Cie (BBC) and Schweizerische Lokomotiv- und Maschinenfabrik (SLM) and entered service in 1899. They were powered by two 110 kW (150 hp) 750V AC electric motors which drove two axles. A two speed gearbox enabled the locomotives to travel at 18 km/h (11 mph) and 36 km/h (22 mph), the latter for passenger transport. The gearbox was later upgraded, raising the speed to 50 km/h (31 mph). Relegated to secondary duties when more powerful designs were introduced, the locomotives provided valuable service until 1930.
