The Chasewater Railway is a former colliery railway running round the shores of Chasewater in Staffordshire, England. It is now operated as a heritage railway.
The line is approximately two miles in length, contained entirely within Chasewater Country Park. The route, which forms a horse-shoe shape around the lake, passes through heathland, including a Site of Special Scientific Interest, and passes over a one-quarter mile long causeway.
Prior to preservation, the line was part of the network operated by the NCB to serve the coalfields of the Cannock Chase area. The exchange sidings, where the colliery line connected with the Midland Railway, were situated about a quarter of a mile north of the current Brownhills West Station.
Significant changes happened in 2002/2003 caused by the closure of the old Brownhills station, due to the building of the M6 Toll motorway. This led to the rebuilding of Brownhills West with significantly improved facilities, including a new carriage shed and heritage centre, and completion of the Chasetown section of the line (the 'Chasetown Extension Railway' between Chasewater Heaths and Chasetown Church Street).
