Indian locomotive class WU

The Indian locomotive class WU was a class of steam locomotives used on broad gauge lines in India.
The four members of the class were built by Vulcan Foundry in Newton-le-Willows, Lancashire, England, to an order placed by the East Indian Railway in 1940. They were completed in 1943.
Proposals were later made for additional members of the class WU to be built. However, the class lacked the ability to cope with post-World War II traffic, and therefore the proposals were never realised. The WUs were still in service on the Eastern Railway Zone in the late 1970s.
