After a series of 0-6-0T tank locomotives developed for the Midland Railway, Henry Fowler's class 3F built for the LMS was the last one in the row. Based on the MR class 2441 built from 1899, these had a smaller boiler with a Belpaire firebox. It got the nickname “Jinty” and is said to have reached speeds of up to 60 mph or 97 km/h, what is exceptional for a locomotive without leading or trailing axles

Between 1924 and 1931, a total of 422 were built by the LMS Horwich works and several commercial manufacturers. Some were used in France in World War II. British Railways inherited 412 and got five back from France. Withdrawals only started in 1959 and were finished in 1967.
