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