The Indian locomotive class '''WCM-5''' is a class of 1.5 [[Volt|kV]] [[Direct current|DC]] [[electric locomotive]]s that was developed in 1956 by [[Chittaranjan Locomotive Works]] (CLW) for [[Indian Railways]]. The model name stands for [[5 ft 6 in gauge railway|broad gauge (W)]], Direct Current (C), Mixed traffic (M) engine, 5th generation (5). The trains were the first locomotive of any kind fully developed and built in India. They entered service in 1961. A total of 21 WCM-5 locomotives was built at CLW between 1961 and 1963.

The WCM-5 served both passenger and freight trains for over 39 years. With the introduction of more modern types of locomotives and 25 KV [[ Alternating current|AC]] electrification, all were withdrawn in early 2000s after repeated failures. Today one locomotive is preserved with rest of the locomotives have been Scrapped.

== History ==
the history of WCM-5 begins in the early 1960s 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 21 1500 V DC electric locomotives from [[Chittaranjan Locomotive Works]] (CLW), who also previously supplied Steam locomotives to India. They are manufactured in India in 1954-1955.They were the last “nosed” locomotives of any type to be manufactured.<ref>{{Cite web|title=Refer pg 282|url=https://rdso.indianrailways.gov.in/works/uploads/File/Data%20Book%20of%20Electric%20Locomotives%202016(3).pdf}}</ref>

The WCM-5 locomotives were used on many Express trains like the [[Deccan Queen]], [[Indrayani Express]] etc as well as in Freight Duties. The Deccan Queen had WCM-5 with a matching livery until 1990s. In mid 1990s the aging WCM-5 began to fail regularly causing disruption in train services. So Central Railways decided to withdraw these locomotive from services and by 2000 ,all units were withdrawn.
