The Midland Railway 1252 class was a class of 30 0-4-4T locomotives built by Neilson and Company in 1875–1876 to the design of Samuel W. Johnson. They were a development of the 6 Class. Originally numbers 1262–1281 and 1252–1261. Under the Midland Railway's 1907 renumbering scheme they became 1236–1265.

Construction history

For this class, the Midland used nominal 5-foot-6 1⁄2-inch (1,689 mm) diameter driving wheels, whereas in all later engines (starting with the 1532 Class) they used nominal 5-foot-3-inch (1,600 mm) diameter wheels. They were given the power classification 1P.

Service history

All except one locomotive passed to the London, Midland and Scottish Railway (LMS) at the 1923 grouping; and nine, Nos 1239/46/47/49/51/52/55/60/61 were still in LMS stock at the end of 1947 and passed to British Railways (BR). BR allocated them numbers 58030–58038, though only three 58033/36/38 received them before withdrawal. The class became extinct in 1954. None was preserved.
