The Midland Railway 1252 class was a class of thirty 0-4-4T locomotives built by Neilson and Company in 1875âÂÂ1876 to the design of Samuel Waite Johnson. They were a development of the 6 Class. Originally numbers 1262âÂÂ1281 and 1252âÂÂ1261. Under the Midland Railway's 1907 renumbering scheme they became 1236âÂÂ1265.
The Midland used nominal diameter driving wheels for this class, whereas in all later engines (starting with the 1532 Class) they used nominal diameter wheels. They were given the power classification 1P.
All but 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 58030âÂÂ58038, though only three 58033/36/38 received them before withdrawal. All members of the class were withdrawn and scrapped by 1954.
