The Midland Railway 1823 Class was a class of twenty 0-4-4T steam locomotives. 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 1532 Class. The 1833 Class followed, and confusingly is sometimes grouped into this class.

Table of orders and numbers^[1]
Original No.	1907 (& LMS) No.	Manufacturer	Works Nos.	Qty	Year	Notes
1823–1832	1331–1340	Derby Works	(order No. 763)	10	1889
1322–1326, 202, 1428–1430, 1697	1341–1350	Derby Works	(order no. 981)	10	1892

Under the 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 Ivatt Class 2 tank locomotives, but only five received their new number. All were withdrawn and scrapped.
