The LMS Stanier Class 5 is a type of steam locomotive designed by William Stanier for the London, Midland and Scottish Railway (LMS). Introduced in the 1930s, it was built for mixed traffic duties, meaning it could haul both passenger and freight trains efficiently. The locomotive features a 4-6-0 wheel arrangement, which provides a good balance of power and stability. A total of 842 units were produced, making it one of the most successful designs of its time. The Class 5 locomotives were known for their reliability and performance, serving various routes across the UK until the decline of steam in the mid-20th century.
