The Gunpowder Railway is a beautifully restored former military narrow‑gauge line running for 1 km through the historic Royal Gunpowder Mills site at Waltham Abbey. Once part of an extensive industrial railway network that carried explosive ingredients between 19th and 20th century processing buildings, the railway has been carefully rebuilt by volunteers to bring this remarkable heritage back to life. Visitors ride in converted RNAD wagons, passing atmospheric woodland, waterways, and original mill structures that tell the story of centuries of explosive innovation, described as “the most important site for the history of explosives in Europe”.

No visit is complete without a tour of the Railway Works, and going into the Ordnance Railway Museum visitors can view demonstration trains showcasing the specialist trucks once used to move gunpowder, cordite, TNT, and other materials around the site.

Since reopening for passenger service in 2022, the railway has become a standout attraction, carrying thousands of delighted visitors each year. Two stations, passing loops, and a growing collection of historic locomotives make the journey both scenic and immersive. With planned extensions and ongoing restoration, the Gunpowder Railway offers a unique blend of history, engineering, and adventure and is a perfect highlight for families, railway enthusiasts, and anyone curious about Britain’s industrial past.
