What is the LMS Coronation Class?

The LMS Coronation Class, also known as the "Duchess" class, was a series of express passenger steam locomotives built by the London, Midland and Scottish Railway (LMS) between 1937 and 1948. Designed by Sir William Stanier, these locomotives were among the most powerful and fastest steam engines in the UK, primarily used for hauling long-distance express services on the West Coast Main Line. A total of 38 LMS Coronation Class locomotives were built during this period.

Key features of the LMS Coronation Class include:

1. Streamlined Design: Early models featured an iconic streamlined casing, aimed at reducing air resistance and enhancing speed. This sleek, Art Deco-inspired design made them visually distinctive.
2. Power and Performance: With a 4-6-2 "Pacific" wheel arrangement, these locomotives were capable of pulling heavy trains at high speeds, often exceeding 100 mph.
3. Service History: They were initially used on prestigious services such as the "Coronation Scot" from London to Glasgow. Post-war, they continued to serve on various important routes until the end of steam on British railways.

Overall, the LMS Coronation Class is remembered for its contribution to the golden age of steam rail travel in the UK, combining engineering excellence with striking aesthetic design.
