Tarka Line

Wikipedia The Tarka Line, also known as the North Devon Line, is a local railway line in Devon, England, linking the city of Exeter with the town of Barnstaple via a number of local villages. Services on the Tarka Line are operated by the Great Western Railway (GWR) and continue across Exeter to terminate at St James Park. In the summer the Dartmoor Railway runs alongside the Tarka Line between Exeter and Yeoford while on summer Sundays GWR services from Exeter operate through to the Dartmoor Railway. The railway broadly follows the route of the A377 road and the River Taw.
