The South Devon Railway engine houses were built in Devon, England, to power the atmospheric trains on the South Devon Railway between Exeter St Davids and Plymouth Millbay railway stations. They contained boilers that provided the power to pumps that created the partial vacuum to move the trains. Three of them still stand largely intact alongside the line.

Exeter St Davids railway station is the principal railway station serving the city of Exeter in Devon, England. It is 193 miles 72 chains from the zero point at London Paddington, on the line through Bristol which continues to Plymouth and Penzance. It is also served by an alternative route to London Waterloo, via Salisbury, and branch lines to Exmouth, Barnstaple and Okehampton. It is currently managed by Great Western Railway and is served by trains operated by Great Western Railway, South Western Railway and CrossCountry. It is the busiest station in Devon, and the third busiest station in South West England.
