The 26 Bristol and Exeter Railway 4-4-0ST locomotives were broad gauge steam locomotives. They first entered service in 1855 and the last was withdrawn in 1892. The Bristol and Exeter Railway was amalgamated into the Great Western Railway on 1 January 1876.
The locomotives were built in four batches, each by a different builder, with variations between them, noticeably in the size of the saddle tank.
