The Indian locomotive class XA was a class of light axle load "Pacific" type steam locomotives used on broad gauge lines in British India, and then in post-partition India and Pakistan.
The 113 members of the class were built by Vulcan Foundry in Newton-le-Willows, Lancashire, England, in 1929/31, 1931 and 1935.
Upon partition in 1947, a total of 37 members of the class went to Pakistan. The other 76 remained in India.
