GWR 5700 Class

The GWR 5700 Class, often written 57xx, is a class of 0-6-0 pannier tank steam locomotives built by the Great Western Railway and British Railways between 1929 and 1950. With 863 built it was the most numerous class of the GWR and one of the most numerous of any British steam locomotive. The GWR officially described them as light goods and shunting engines, but they were also used on branch, suburban and shorter main-line passenger trains across the network and later across the Western Region and other regions of British Railways. The 1955 Modernisation Plan led to withdrawal between 1956 and 1966. Nineteen withdrawn engines were sold to the London Transport Executive and industry, and ten of these were later preserved.
