The Indian locomotive class '''WCM-1''' is a class of 1.5 [[Volt|kV]] [[Direct current|DC]] [[electric locomotive]]s that was developed in 1951 by [[Vulcan Foundry]] and [[English Electric]] for [[Indian Railways]]. The model name stands for [[5 ft 6 in gauge railway|broad gauge (W)]], Direct Current (C), Mixed traffic (M) engine, 1st generation (1). They entered service in 1955. A total of 7 WCM-1 were built in England between 1954 and 1955.

The WCM-1 served both passenger and freight trains for over 45 years. With the introduction of more modern types of locomotives and 25 KV [[ Alternating current|AC]] electrification, all were withdrawn by early 2000s after repeated failures. Today 1 locomotive is preserved with rest of the units being Scrapped.
== History ==

The history of WCM-1 begins in the early 1950s with the stated aim of the [[Indian Railways]] (IR) to remove the aging fleet of WCG-1 and WCP-1 class locomotives working in the [[Central Railway zone|Central Railways]] (CR) .<ref>{{Cite book| title=Vulcan Foundry Locomotives 1832–1956| last=Gudgin| first=D.S.E.| publisher=Bradford Barton| location=Truro| year=1976| isbn=978-0-85153-215-8}}</ref> So IR to procure 7 1500 V DC electric locomotives from [[English Electric]] and [[Vulcan Foundry]], the latter previously supplied Steam locomotives to India. They are manufactured in England and shipped to India in 1954-1955.

These locomotives were the first mixed class electric locomotive to roam India as well as the first electric locomotive with now common [[Co-Co locomotives|Co-Co]] wheel arrangement.<ref>{{Cite web|title=Refer pg 252|url=https://rdso.indianrailways.gov.in/works/uploads/File/Data%20Book%20of%20Electric%20Locomotives%202016(3).pdf}}</ref> They were also the longest non steam locomotive in India until the arrival of the [[Indian locomotive class WAG-12|WAG-12]] class. Initially the WCM-1 class were known as EM/1 class. They were easily recognizable with their huge size and round smooth noses. They had their cab doors placed in the middle of the body instead of being near the cab.

The WCM-1 locomotives were used on many Express trains like the [[Deccan Queen]], [[Indrayani Express]] and as well as in Freight Duties. In 1968, the placement of the entry doors were moved to near the cab for better practicality. The Deccan Queen had WCM-1 with a matching livery until 1990s. In the mid 1990s the aging WCM-1 began to fail regularly causing disruption in train services. So Central Railways decided to withdraw these locomotives from services and by 2000, all units were withdrawn.
