In the 1907 Midland Railway renumbering scheme these became numbers 1351–1380.

In March 1948 BR allocated them the numbers 58059–58072 to make room for LMS Ivatt Class 2 2-6-2T locomotives, but only eleven actually received their new numbers.

They were built with typical Midland-pattern Johnson boilers with the flared safety valve housing.

Some were later rebuilt with LMS pattern boilers with a Belpaire firebox and smaller pop valves.

Some had condensing gear fitted for working the 'Widened Lines' tunnels of the Metropolitan Railway.
