The Great Western Railway (GWR) 8000 or Cathedral Class was a class of proposed 4-6-2 steam locomotive. This locomotive class would have been the GWR's second attempt at designing a 4-6-2 locomotive, following No. 111 The Great Bear.^[1]^[2]^[3]

History

Proposal

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

Design

The 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 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 smokebox from the GWR Star Class.^[2]

The locomotive was to have a boiler pressure of 250 psi (1.7 MPa).^[3] The locomotive's tractive effort was raised from 31,625 lbf (140.68 kN) on the Castle Class to 40,300 lbf (179 kN) on the Cathedral Class.^[3] The 6 ft 6 in (1.98 m) driver diameter on the King Class was kept for the Cathedral Class.^[1]

In games

Caledonia Works made a model of the Cathedral Class for Train Simulator 2022, even writing their own history for the class.^[4]
