The GWR Cathedral Class (also known as the GWR 8000 Class) was a proposed 4-6-2 "Pacific" steam locomotive design that would have been the GWR's second attempt at a 4-6-2 "Pacific" type locomotive after their first attempt, the GWR 111 The Great Bear.[1][2][3]

History

Proposal

The proposal for the GWR Cathedral Class was submitted by Frederick W. Hawksworth in 1941. It was designed for post-war rail traffic.[1]

Design

The GWR Cathedral Class would have featured similar features from other locomotives in the UK, such as having 4-cylinders, an all-new tender design from the GWR Hall Class and 1000 "County" Class that would come years later, same pony truck from the King Class 4-6-0s, different trailing bogie design coming from the LMS Princess Royal Class 4-6-2 Pacifics and, the same body design from the LMS Princess Royal Class 4-6-2 Pacifics but designed with the same smokebox design from the GWR Star Class.[2]

The locomotive was also designed to have its boiler pressure raised from the 225 psi (1.55 MPa) on the GWR Castle Class to 250 psi (1.7 MPa) for the Cathedral Class.[3] The locomotive's tractive effort was raised from 31,625 lbf (140.68 kN) on the GWR Castle Class to have 40,300 lbf (179 kN) on the Cathedral Class.[3] The driver diameter on the GWR Castle Class was 6 ft 8+12 in (2.045 m), but when designing the Cathedral Class, they lowered the diameter on the driving wheels to 6 ft 3 in (1.91 m).[3]
