The '''Midland Railway 990 class''' was a class of [[4-4-0]] [[steam locomotive]] with simple expansion. Ten were built by the [[Midland Railway]] in 1907–1909. They shared many features with the [[Midland Railway 1000 Class|1000 class]] [[compound locomotive|compounds]]. Initially built as saturated, from 1910 to 1914 they were equipped with [[superheater|superheated]] boilers. These locomotives were notable for their work north of Leeds, over the difficult Settle and Carlisle route.
==Accidents and incidents==
:{{main|1913 Ais Gill rail accident}}
*On 2 September  1913, locomotive No. 993 was hauling a stalled express passenger train that was involved in a collision with another express at [[Ais Gill]], [[Westmorland]] due to the latter [[Signal passed at danger|passing signals at danger]]. The other train was hauled by [[Midland Railway Class 2 4-4-0]] No. 446. 16 people were killed and 38 were injured.<ref name=G&H>*{{cite book |first1=Malcolm |last1=Gerard |first2=J. A.

==Withdrawal==
They passed to the [[London, Midland and Scottish Railway]] (LMS) in 1923 and were withdrawn between 1925 and 1929. In 1926, the eight surviving locomotives were renumbered 801 to 809 to free up their old numbers for more compounds. None were preserved, though the first of the compounds was.
