Dartmouth Steam Railway

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.

The line is owned and operated by Dart Valley Railway Limited. This company also owns Dart Pleasure Craft Limited, which operates the Dartmouth Passenger Ferry as well as river and coastal cruises. The railway and connecting boat and bus services are jointly promoted as the Dartmouth Steam Railway and River Boat Company.

Unusually amongst heritage railways, it is a commercial operation which does not rely on volunteer labour or charitable donations, although a few volunteers help at Churston railway station.
