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. The first was delivered in 1851, and the last withdrawn in 1880. On 1 January 1876, the Bristol and Exeter Railway was amalgamated with the Great Western Railway, after which the surviving locomotives were given new numbers.
