History

A total of 197 engines were built. 192 of them were sequentially numbered 3835–4026 for the Midland Railway. After nationalisation in 1948 British Railways added 40000 to their numbers so they became 43835–44026. Five engines were constructed by Armstrong Whitworth for the Somerset and Dorset Joint Railway in 1922, numbered 57–61. They were absorbed into LMS stock in 1930, becoming 4557–4561.

Accidents and incidents
  • On 19 November 1926, locomotive No. 3980 was one of two hauling a freight train. One of the private owner wagons disintegrated, derailing the train at Parkgate and Rawmarsh, Yorkshire. A signal post was partly brought down, obstructing an adjacent line. The carriages of an express passenger train had their sides ripped open by the signal post. Eleven people were killed.[1]
  • On 6 March 1930, locomotive No. 4009 was hauling a ballast train that was in collision with a passenger train at Langwathby station, Cumberland. The passenger train had departed from Culgaith against signals. Two people were killed and four were seriously injured.[2]

Withdrawal

The 197 engines in this class were withdrawn between 1954 and 1965 as follows:
