Transport for Wales (TfW) customers are being advised to plan their journeys carefully with services set to be disrupted by two days of national industrial action.

The National Union of Rail, Maritime, and Transport Workers (RMT) has announced strike action will take place on Wednesday (July 27) and train drivers’ union, ASLEF, has announced its members will strike on Saturday, July 30.

TfW is not involved in either dispute but its services will be affected, particularly today when the majority of services on the Wales and Borders network will be suspended.

Further disruption is expected on Thursday due to the shift patterns of Network Rail’s signallers and the significant challenges moving trains and crew to operate between strike days there is likely to be disruption.

Customers are urged to check their journey before they travel.

On Saturday, TfW will be running a full timetable but services are likely be impacted by strike action at other train operating companies.

A spokesperson said: “Customers with existing non-season tickets valid for travel on Wednesday, July 27 and Saturday, July 30 can use those tickets anytime between Tuesday, July 26 and Tuesday, August 2. Customers are encouraged to avoid travelling on Friday, July 29 and Sunday, July 31 as services are expected to be extremely busy.

“Alternatively, customers can claim a full refund, with no admin fee charged. Season ticket holders can apply for compensation via Delay Repay.

In the meantime, we’re suspending sales of Advance tickets for the strike dates in order to minimise the number of people disrupted. We’re advising customers continue to check the TfW or Traveline websites, and those of other operators, for updates.”
