Replacement buses and the Barry route

Replacement buses will run between Cardiff Central and Bridgend via Pontyclun. A reduced train service will run between the two cities via Barry, with longer journey times. TfW warns that replacement vehicles may be busier than usual and advises passengers to allow extra time.

Saturday service changes

TfW plans two trains an hour between Cardiff Central and Barry Island, two between Coryton and Penarth, and four between Cardiff Central and Rhymney or Bargoed. Caerphilly to Penarth trains will not run.

One train an hour will run between Cardiff Central and Bridgend, calling only at Barry, Rhoose Cardiff International Airport and Llantwit Major. Every two hours that service will extend to or from Swansea. Maesteg to Cardiff Central trains will run only between Maesteg and Bridgend.

London to Swansea reduced to hourly

Great Western Railway trains will also avoid the Pontyclun route. TfW's planned works page says London Paddington to Swansea will run once an hour and divert via Barry without calling there. Several early and evening trains are altered, so passengers should check the journey planner before setting out.
