Electrification

We’re already running new electric-powered trains, and Network Rail is upgrading the route between Cardiff Central and Bristol Parkway 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.

January to March

Buses/coaches will replace trains between Newport and Bridgend (including Cardiff Central) on Sunday 10 February and 31 March

  • trains between London Paddington and South Wales will start/terminate at Bristol Parkway
  • shuttle trains will run between Swansea and Bridgend
  • services from Portsmouth Harbour to Cardiff Central will terminate at Newport

Buses/coaches will also replace trains between Bristol Parkway and Cardiff Central on Sunday 17 February.

  • trains between London Paddington and South Wales will start/terminate at Bristol Parkway
  • shuttle trains will run between Swansea and Cardiff Central
  • services from Portsmouth Harbour to Cardiff Central will terminate at Bristol Parkway, or Bristol Temple Meads

In addition, trains will run to an amended timetable due to reduced capacity on the railway in the Cardiff area on Saturday 23 and Sunday 24 March.

Looking ahead

Work is also due to take place to install electrical equipment inside the Severn Tunnel, affecting services between Newport and Bristol Parkway on the following dates:

  • Friday 19 April (Good Friday) to Monday 22 April (public holiday)
  • Saturday 27 and Sunday 28 April

Some trains will be diverted and buses/coaches will replace trains between Newport, Severn Tunnel Junction, Patchway and Bristol Parkway.

More information about the impact of this upgrade work on train services will be made available in due course.

Additional engineering work is planned by Network Rail at weekends through the summer and into the autumn, which will affect services to and from South Wales.
