The Patriot Class was a class of 52 express passenger steam locomotives built for the London Midland and Scottish Railway. The first locomotive of the class was built in 1930 and the last in 1934. The class was based on the chassis of the Royal Scot combined with the boiler from Large Claughtons earning them the nickname Baby Scots. A total of 18 were rebuilt to create the LMS Rebuilt Patriot Class between 1946 and 1948; thereafter those not subjected to rebuilding were often referred to as the Unrebuilt Patriot Class. These remaining 34 unrebuilt engines were withdrawn between 1960 and 1962.
