The Indian locomotive class XS was a class of experimental four-cylinder 4-6-2 "Pacific" type steam locomotives used on 5 ft 6 in (1,676 mm) broad gauge lines in British India, and then in post-partition Pakistan.[2][3]

The four members of the class were built by Vulcan Foundry in Newton-le-Willows, Lancashire, England, in 1930. They were divided into two sub-classes, XS1 and XS2, each made up of two locomotives.[1][3] Upon the partition of India in 1947, they all went to Pakistan.[2]
