The Dartmouth Steam Railway, formerly known as the Paignton and Dartmouth Steam Railway, is a 6.7-mile (10.8 km) heritage railway on the former Great Western Railway branch line between Paignton and Kingswear in Devon, England. Much of the railway's business is summer tourists from the resorts of Torbay who are transported to Kingswear from where the Dartmouth Passenger Ferry takes them across the River Dart to Dartmouth.
