The railway originated as a coal-carrying wagonway, predating the birth of the modern steam locomotive industry.
Causey Arch was engineered by Ralph Wood and remains a Grade I listed structure.
The line connects three distinct stations, each providing different perspectives of the industrial heritage site.
The railway holds a collection of locomotives that were originally built for local North East collieries.
The site was originally commissioned to transport coal from the Tanfield coalfield to the River Tyne.
The wooden rails of the original 1725 wagonway were replaced by cast iron plates, then later by wrought iron rails, marking a key evolution in transport history.
The Tanfield Railway is the world's oldest operating railway, with roots dating back to 1725 as a wooden wagonway. It operates a standard gauge line running between East Tanfield, Andrews House, and Sunniside stations in County Durham. The route traverses the Causey Arch, the oldest surviving railway bridge in the world, built in 1725 to span the deep Tanfield Gorge. The museum preserves an extensive collection of industrial locomotives, passenger carriages, and vintage freight wagons. Operations rely on steam locomotives that regularly pull visitor trains through the historic Derwent Valley landscape. It serves as a living museum, demonstrating the evolution of coal-hauling technology from the 18th century to the mid-20th century. The East Tanfield station serves as a primary terminus, offering car parking and direct access to the rolling stock displays. All operations are volunteer-run, maintaining the site as a working heritage attraction rather than a static exhibit.

Check the official website for the specific operational schedule, as steam train services run on a rotating timetable.
Wear sturdy footwear suitable for walking on gravel station platforms and potentially muddy paths near the gorge.
Bring a camera, as the steam locomotives and the 18th-century arch provide rare industrial photography opportunities.
Do not attempt to walk along the tracks outside of designated public areas, as this is a working railway site.
Operations are seasonal, typically running on weekends and bank holidays, with limited mid-week service during school holiday periods.
Stay clear of the tracks and behind the yellow lines while trains are moving or approaching; follow all volunteer staff instructions.
