Behold the 'Miniature Mainline'—a 13.5-mile masterpiece of engineering tracing the Kent coast from Hythe to the otherworldly landscape of Dungeness. Conceived in the 1920s as a high-speed passenger artery in one-third scale, the RH&DR features world-famous scale steam locomotives that operate with the efficiency of a full-size main line. A uniquely British marvel, it preserves a vital wartime legacy as a supply route for PLUTO, all while traversing the tranquil vistas of the Romney Marsh.
The Miniature Mainline
The RH&DR is a masterpiece of engineering. Originally conceived in the 1920s as a "proper railway" on a smaller scale, it connects the remote communities of the Romney Marsh. During WWII, it became the only miniature railway to be officially mobilized, used to deploy the PLUTO (Pipe-Line Under The Ocean) fuel pipeline to France. Today, its 11 steam engines continue to run at speed, offering a unique "railway in miniature" experience.
