The Midland Railway 1252 class was a class of thirty 0-4-4T locomotives built by Neilson and Company in 1875–1876 to the design of Samuel Waite 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.

The Midland used nominal 5-foot-6+1⁄2-inch (1,689 mm) diameter driving wheels for this class, 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.
