The 13 3⁄4-mile (22.1 km) line runs from the Cinque Port of Hythe via Dymchurch, St. Mary's Bay, New Romney and Romney Sands to Dungeness, close to Dungeness nuclear power station and Dungeness Lighthouse.
  The railway was the dream of millionaire racing drivers Captain John Edwards Presgrave ("Jack") Howey and Count Louis Zborowski. The latter had constructed a railway at Higham Park, his home at Bridge, Kent, and agreed to donate the rolling stock and infrastructure to the project. However, he was killed on 19 October 1924 in a motor racing accident at the Monza Grand Prix before the Romney Marsh site was chosen, and Howey continued the project alone.
