Manufacturer description
The idea for a new class of two cylinder, 4-6-0, mixed traffic locomotive on the Great Western Railway came from George Churchward, Chief Mechanical Officer at the time, in the years preceding the First World War. His proposal envisaged combining the standard Swindon No.1 boiler with driving wheels of 5' 8" to deliver a combination of good pulling power and good acceleration which is vital in the design of an efficient mixed traffic locomotive.
