An engine shed was opened at Exeter by the Bristol and Exeter Railway when it opened the line to here in 1844. A second facility was added a few years later by the South Devon Railway and the two were combined under the Great Western Railway (GWR) in 1876. The Bristol and Exeter had been worked by the GWR until 1849 but then purchased its own locomotives. Temporary workshops for these were built at Exeter but a permanent facility at Bristol was opened in 1851.
