Parts of the line are single track, meaning that trains travelling in opposite directions must sometimes wait for each other. The full journey from Barnstaple to Exeter takes just over 1 hour, on-par with the journey time in a car. Beyond Barnstaple, the railway used to continue to Ilfracombe or Instow and Bideford. Part of the latter route is preserved as the Bideford & Instow Railway, while sections of both routes have been reopened as cycleways on the Tarka Trail.
