GWR 0-6-0PT

The GWR 0-6-0PT (pannier tank), is a type of steam locomotive built by the British Great Western Railway with the water tanks carried on both sides of the boiler, in the manner of panniers. They were used for local, suburban and branch line passenger and goods traffic, for shunting duties, and as banker engines on inclines. The early examples, such as the 1901 and 2021 classes, were rebuilt from saddle or side tanks when the locos received a Belpaire firebox – this type of firebox has a square top and is incompatible with a curved saddle tank. This process mostly took place during the tenure at Swindon Works of George Jackson Churchward. Only a very small number of saddle tank locomotives escaped rebuilding as panniers, notably the 1361 Class built new under Churchward in 1910, by which date a few of the 1813 Class had already been rebuilt as pannier tanks.

Preservation

In fiction

• In The Railway Series of children's books by the Wilbert Awdry and the television series Thomas & Friends the character Duck the Great Western Engine is based on a 5700 Class pannier tank.
• No. 5775 is in the 1970 film The Railway Children, in a brown livery, with the initials of the fictitious Great Northern and Southern Railway on the tank sides.
• No. 6412 is in the 1970s children's TV series The Flockton Flyer.^[1]
• No. 5764 is in the 1976 short film "The Signalman", loosely based on the Charles Dickens book of the same name.
