Plym Valley Railway occupies a heritage railway site at Marsh Mills Station on Coypool Road in Plympton, south of Plymouth city centre. The railway operates vintage steam and diesel trains along a restored section of track, offering visitors a chance to experience early 20th-century rail travel. The museum is wheelchair accessible and welcomes families and railway enthusiasts throughout the year.
The station and associated buildings preserve period architecture and working railway infrastructure. Visitors can ride restored carriages, explore locomotives on display, and learn about the history of rail transport in Devon. The site includes a small museum, a cafe, and a gift shop. Opening hours and special event days vary seasonally, so checking the website before a visit is recommended. Plympton itself is easily reached by bus from Plymouth city centre, making the railway a straightforward day trip for those interested in industrial heritage and transport history.
