The Midland Railway 990 class was a class of 4-4-0 steam locomotive. Ten were built by the Midland Railway in 1908–1909, with simple expansion, to compare with the 1000 class compounds, with which they shared many features. Initially saturated, they were later superheated. These locomotives were well known for their work North of Leeds, over the demanding Settle and Carlisle route.
Accidents and incidents
- Main article: 1913 Ais Gill rail accident
- On 2 September 1913, locomotive No. 993 was one of two hauling an express passenger train that was in a collision with a pair of light engines at Ais Gill, Westmorland due to a signalman's error. Sixteen people were killed and 38 were injured.[1]
Withdrawal
They passed to the London, Midland and Scottish Railway (LMS) in 1923 and were withdrawn between 1925 and 1928. None has survived to preservation, though the first of the compounds has.
