The LMS Black Five is a type of steam locomotive built by the London, Midland and Scottish Railway (LMS) in the 1930s. Designed by engineer William Stanier, these locomotives were known for their versatility and reliability, making them suitable for both passenger and freight services. A total of 842 units were produced, and they became a common sight on British railways. The Black Five features a 4-6-0 wheel arrangement, which means it has four leading wheels, six driving wheels, and no trailing wheels. This design allowed for good stability and power. Many of these locomotives continued to operate long after their initial production, and some are preserved today, showcasing the engineering excellence of the era.
