We’re already running new electric-powered trains, and Network Rail is upgrading more routes so we can provide faster journey times.
As a result, on various dates, some services will run to an amended timetable; others will be replaced by buses or coaches and some journey times may be longer than normal.

Check before you travel at GWR.com/Check.

Please note: for a temporary period, Network Rail is unable to confirm train timetables as far in advance as usual. As a result, we expect online journey planners to be updated in the weeks leading up to periods of rail improvement work. For the latest information, please check your journey details immediately prior to travelling.

Bristol Parkway area

13 to 14 October

Further work to complete the installation of overhead electrical equipment at Bristol Parkway is due to take place on Saturday 13 and Sunday 14 October.

Network Rail also plans to carry out work between Bristol Parkway and Bristol Temple Meads (including the Severn Beach line) that weekend.

  • between London Paddington and Cheltenham Spa, most services are not expected to run; a shuttle train between Swindon and Cheltenham Spa is expected to operate instead
  • from Great Malvern, Worcester Shrub Hill or Gloucester towards Bristol, trains are expected to terminate at Yate – replacement coaches will operate to Bristol Temple Meads

Newbury area

Network Rail is also working to electrify the route between Reading and Newbury to reduce journey times between London and the South West.

Long-distance services will continue to run during upgrade work using a different route – meaning some journey times may be up to 30 minutes longer.

Connecting coaches will replace trains to/from stations between Pewsey and Theale during August as well as in October and November.

For more information, visit GWR.com/Newbury2018.

South Wales

Up until 2 December

There will be reduced capacity at weekends on the lines between Newport and Cardiff Central whilst Network Rail carries out upgrade work linked to electrification.

Trains will continue to run but may take longer than usual. We would recommend that you check your journey before you travel at GWR.com/Check.

Looking ahead, Network Rail will continue its programme to electrify the route through South Wales during 2019.

Information about the impact of this upgrade work on train services will be made available once the details have been agreed.
