Indian locomotive class YD

The YD class was a class of 2-8-2 tender locomotives built for the metre-gauge railways of British India, designed to the Indian Railway Standard. In early 1927 Vulcan Foundry built ten 2-8-2 goods locomotives for the Assam Bengal Railway, later known as class YD/1, and from mid-1927 the YD was mass-produced for other railway companies as a development of those ten, with a four-axle bogie tender in place of their three-axle one. Between 1927 and 1953 at least 270 were built by eight manufacturers in Germany, the United Kingdom, India, Japan and Czechoslovakia. After 1957 the 143 left in India were renumbered 30154 to 30296 and the YD/1 became 30297 to 30306. Pakistan, Bangladesh and Burma also ran them, and Vulcan Foundry built three similar 2-6-2 locomotives for the North Borneo Railway in 1955, among the last steam locomotives it built. Several are on display in railway museums in India, Bangladesh, Myanmar and Pakistan.
