Disruption to TfW services this December and January – check before you travel

Disruption to TfW services this December and January – check before you travel

09 December 2022

Rail passengers are being warned to prepare for disruption across the Wales and Borders network during December and January.  

The National Union of Rail, Maritime, and Transport Workers (RMT) have announced strike action will take place on 13-14, 16-17 and 24-27 December and 3-4 and 6-7 January.

This will significantly disrupt the rail network across the whole of Wales, England and Scotland.

Transport for Wales is not involved in the industrial action. However, the industrial action resulting from the dispute between the unions and Network Rail means TfW will be unable to operate rail services on Network Rail infrastructure.


Industrial action

13-14 and 16-17 December and 3-4 and 6-7 January – only services in and around Cardiff will be able to operate

The majority of services across the Wales and Borders network will be suspended. As on previous strike days, an hourly service will run between Cardiff and Newport, Treherbert, Aberdare, Merthyr Tydfil and Rhymey.

No other services across the Wales and Borders network will be able to operate on strike days.

On 15 December and 5 January, a full timetable will operate but services will start later than normal – night shift signalling shifts will be affected by the strikes, so services can only start when early shift signallers arrive for duty.

24-27 December

Services will finish earlier than normal on 24 December and start later on 27 December due to the industrial action. There are no services on 25 and 26 December.

Jan Chaudhry-Van der Velde, Transport for Wales Chief Operations Officer, said: “The Christmas and New Year period is traditionally a very busy time for the rail industry and this year with a number of strike days taking place throughout December and January it’s vital passengers check for the latest information before making their journeys.

“We are continuing to advise people to only travel by rail on strike days if they have checked on journey planners first.  Despite not being involved in the strikes, only around 10% of our services will be running and the majority of the Wales and Borders network will have no services at all.”


Other operators - Great Western Railway

GWR will be able to operate to/from Cardiff on 13/14/16 December and 3/4/6 January, but not on either Saturday 17 December or 7 January.

Great Western Railway services will not be running on Christmas Day or Boxing Day.

Tuesday 27 to Saturday 31 December

Trains between London and South Wales will run but will be diverted between Swindon and Newport – extending journey times by around 25 minutes.

  • An hourly service will operate between London Paddington and Swansea
  • These trains will stop additionally at Patchway
  • Shuttle buses are planned between Patchway and Bristol Parkway
