The Midland Railway (MR) 2441 Class was a class of steam locomotive. Introduced by Samuel Johnson in 1899, originally with round-topped fireboxes. Henry Fowler later rebuilt them with Belpaire fireboxes. They were given the power classification 3F. The LMS Fowler Class 3F of 1924 was based on this design.

Numbering

Sixty locomotives were built. Initially numbered 2441–2460, 2741–2780; they were renumbered 1900–1959 in the Midland Railway's 1907 renumbering scheme. All passed to the London, Midland and Scottish Railway, initially retaining their MR numbers, before being renumbered 7200–7259 between 1934–1937. All passed into British Railways ownership in 1948 and were numbered 47200–47259.

Withdrawal

Withdrawals started in 1954, with three locomotives still in service on 1 January 1966. All were scrapped, though several later LMS locomotives have survived.
