The Wales & Western region includes more than 2,700 miles of railway with a 5,500-strong workforce. We serve communities and businesses of Wales, the Thames Valley, West of England and the South West Peninsula.

Wales has approximately 923 miles (about 1,485 kilometers) of railway track. This network is managed by Network Rail and forms a vital part of the "Wales & Western" region. The system includes major corridors like the North Wales Coast Line and the South Wales Main Line, which connect to the UK's broader high-speed network. Interestingly, while the mainline mileage is around 923, the region is also home to many "Great Little Trains of Wales"—heritage narrow-gauge railways like the Ffestiniog and Snowdon Mountain Railway—which add dozens of miles of additional track used primarily for tourism. In 2026, the network is undergoing significant modernization, including the "South Wales Metro" project, which aims to electrify and upgrade the Core Valley Lines around Cardiff to provide more frequent, "metro-style" service to the surrounding communities.
