The Exeter to Plymouth railway of the London and South Western Railway (LSWR) was the westernmost part of a route competing with that of the Great Western Railway (GWR) and its 'associated companies' from London and Exeter to Plymouth in Devon, England. Whereas the GWR route from Exeter followed the coast to Newton Abbot and then went around the southern edge of Dartmoor, the LSWR route followed the northern and western margins of Dartmoor, passing through the towns of Crediton, Okehampton, and Tavistock.

Crediton is a town and civil parish in the Mid Devon district of Devon, England. It stands on the A377 Exeter to Barnstaple road at the junction with the A3072 road to Tiverton, 7 miles (11 km) north west of Exeter and 14 miles (23 km) from the M5 motorway. It has a population of 21,990.
