The Selby Diversion is a railway infrastructure project on the East Coast Main Line (ECML) in North Yorkshire, England. Constructed in the early 1980s and opened to traffic in 1983, the diversion created a new section of line that bypasses the town of Selby.
Purpose and Background
The original ECML route passed through Selby and was increasingly vulnerable to ground movement caused by extensive coal mining in the Selby Coalfield. To maintain the reliability and safety of the main north‑south rail corridor, British Rail commissioned a new alignment that avoided the affected area.
Construction and Route
- Length: Approximately 7 mi (11 km) of new track.
- Key Features: The new alignment includes a modernised double‑track section, updated signalling, and bridges crossing the River Ouse and other waterways.
- Cost: The project was funded at a reported cost of around £44 million (adjusted to 1980s values).
Operational Impact
- The Selby Diversion became the primary route for fast intercity services between London, York, Newcastle, and Edinburgh, effectively replacing the former Selby‑through section for long‑distance traffic.
- Selby station remained in operation but was re‑classified as a secondary stop, served mainly by regional and local services rather than the high‑speed ECML trains.
Current Status
The diversion continues to form an integral part of the ECML, handling a substantial proportion of the United Kingdom’s intercity passenger and freight traffic. Regular maintenance and periodic upgrades (e.g., signalling enhancements) are undertaken by Network Rail, the infrastructure owner.
