Midland Railway 990 Class
The Midland Railway 990 class was a class of 4-4-0 steam locomotive. Ten were built by the Midland Railway in 1907–1909, with simple expansion, to compare with the 1000 class compounds, with which they shared many features. Initially built as saturated, from 1910 to 1914, they were equipped with superheated boilers. These locomotives were well known for their work North of Leeds, over the demanding Settle and Carlisle route.

- 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.
