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[edit]

For this class, the Midland used nominal 5-foot-6 12-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[edit]

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.
