GWR 3150 Class

The Great Western Railway (GWR) 3150 Class was a class of 2-6-2T side tank steam locomotive.

History
Churchward based the 3150 class on his 3100 (later 5100) class. They used the larger and heavier Standard 4 boiler and so had greater boiler capacity, but were consequently heavier and thus restricted to Red routes. They were principally heavy suburban passenger traffic engines. Five of the class were rebuilt into the Collett 3100 Class. None of the class were preserved.
