The Dartmoor line is a 15+1⁄2-mile (24.9 km) railway line in Devon, England. From Crediton, the line runs alongside the Tarka Line to the site of the former Coleford Junction where it diverges west to Okehampton. Previously a heritage line, it is owned by Network Rail. From 1997 to 2019, the line was operated as a heritage railway by the Dartmoor Railway community interest company. During this time, Great Western Railway ran a public service between Exeter and Okehampton on summer Sundays. Meldon quarry was mothballed in 2011, ceasing the use of the line for freight.
