The Strawberry Line is a length of gauge railway inside Avon Valley Country Park (near Keynsham). It is Britain's only commercial ground-level railway. As a conventional it provides train rides for visitors to the park (for an additional fare), but it also runs demonstration freight trains using correctly scaled wagons. Driver experience courses are offered in the winter.
The railway was started at the Avon Valley Country Park in May 1999, with the first trains running on a demonstration track.
An area is set aside for the coaling and preparation of steam locomotives, including a fire-dropping pit.
The whole railway is in the process of being resignalled with track circuits replacing the treadle-operated signalling system. The signalling recreates the prototypical railway operational scenario, with signals not clearing unless the section ahead, or the intersecting line, is clear.
