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 from summer tourists from the resorts of Torbay, who travel to Kingswear, where the Dartmouth Passenger Ferry takes them across the River Dart to Dartmouth.
