The seven Bristol and Exeter Railway 2-2-2WT locomotives were small 2-2-2 well tank locomotives designed by James Pearson for working branch lines such as those to Tiverton and Clevedon, as well as acting as pilot locomotives at Bristol.[1] The first was delivered in 1851, and the last withdrawn in 1880.
