The BR Standard Class 6 is a type of steam locomotive designed by the British Railways in the 1950s. It was built for mixed traffic duties, meaning it could handle both passenger and freight services efficiently. The design features a 2-6-0 wheel arrangement, which provides a good balance of power and stability. These locomotives were known for their reliability and versatility, with a total of 80 units produced. They were part of the broader BR Standard Class series, which aimed to modernize British railways after World War II. The Class 6 locomotives were primarily used in the UK until the decline of steam in the 1960s.
