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, we sometimes need to run an amended timetable, or replace trains with coaches.

Here are some key dates to be aware of, but we recommend checking journeys before you travel, especially at weekends.

Connecting coaches and buses will replace trains between Bristol Parkway and Cardiff Central on the following dates:

  • Sunday 22 September (until 14:00)
  • Sunday 29 September (until 14:00)
  • Sunday 13 October (until 14:00)

On these dates, trains will run between London Paddington and Bristol Parkway, then restart from Cardiff Central to Swansea.

Connecting coaches will replace trains between Bristol Parkway and Bridgend on the following dates:

  • Saturday 19 October
  • Sunday 20 October

On these dates, trains will run between London Paddington and Bristol Parkway, then restart from Bridgend to Swansea.

Trains will also run between Portsmouth Harbour and Bristol Parkway as well as between Taunton and Bristol Temple Meads (Saturday 19 October only).

Looking ahead

Coaches will replace all train services via Bristol Parkway due to re-signalling work on Saturday 26 and Sunday 27 October.

Further engineering work is planned affecting trains between Bristol Parkway and Bristol Temple Meads on Sunday 3 November.

From Sunday 15 December 2019 the times of trains will be changing, we’ll be running more services on key routes and many journey times will be faster.

Work is also due to take place in the Newport area and at Cardiff Central station over the Christmas period affecting services to/from South Wales.
