Keeping you moving

This record investment means that we’ll be doing more work to improve the railway across the South West and into London than ever before.  We’ll do most of the work when trains are not running, but will need to work at weekends, bank holidays and during school holiday times.

If you are planning to travel at the weekend or during a holiday period, don’t get caught out.  Always check before you travel at National Rail Enquiries or with your relevant train operator CrossCountry, Great Western Railway, Southern or South Western Railway.
