They had the [[power classification]] 1P.

==History== They were built in two batches of 10 each at Derby in 1889 and 1892. They were a development of the [[Midland Railway 1532 Class|1532 Class]]. The [[Midland Railway 1833 Class|1833 Class]] followed, and confusingly is sometimes grouped into this class.

Under the [[Locomotives of the Midland Railway#Numbering and classification|Midland Railway 1907 renumbering scheme]], they were given the numbers 1331–1350. The [[London, Midland and Scottish Railway]] numbers were the same. Seven, numbers 1337/40–42/44/48/50 were inherited by [[British Railways]] in 1948. In March 1948 they were allocated the numbers 58052–58058 to create space in the ex-LMS numbering series for [[LMS Ivatt Class 2 2-6-2T|Ivatt Class 2 tank]] locomotives, but only five received their new number. All were withdrawn and scrapped.
