The class was designed for the LMS by Henry Fowler but owes its origins to a Midland Railway 0-6-0 tank engine designed by Johnson. The 'Jinty' became the company's standard 0-6-0 tank shunting engine and 422 were built between 1924 and 1931. So large was the order that much of the work was contracted out. They were highly versatile engines and found themselves let out of the shunting yards to pull both freight and passenger trains. Seven spent a period on the Somerset & Dorset Joint Railway, returning to the LMS in 1930. Two were re-gauged to 5'3" and sent to Northern Ireland in 1944 and carried Northern Counties Committee livery. These were reclassified as Y Class locomotives. In the mid 1950s, the 'Jintys' were displaced in the yards by diesel shunters but some survived in service to the last days of steam. Ten have been preserved, being snapped up early on by preservation societies. Our example is 372-206 in black with early BR insignia and numbered 47231.
