GWR 5400 Class

The Great Western Railway 5400 Class was a class of 0-6-0 pannier tank steam locomotives, smaller than the ubiquitous 5700 Class. Nominally a Collett design, the class had 5 ft 2 in driving wheels for greater top speed with autocoaches and was fitted with the remote control gear needed for push-pull autotrains, with a modern cab and a larger bunker, and the engines were frequently seen on inner suburban routes from Paddington. The prototype, No. 5400, was rebuilt from 2021 Class No. 2062 in 1930 but lasted only two years before being scrapped as a parts donor for an all-new engine of the same number, and 25 locomotives were built, numbered 5400 to 5424. The rounded-edge cab they introduced was fitted to all later GWR pannier tank designs. Withdrawal began in 1957 and was completed in 1963.
