Wales: Train strikes set to cause delays and disruption

However, it warned services are likely to be particularly busy.

Aslef members at 16 train operators across the UK are taking part in the strike.

Three of those, which do not operate in Wales, will walk out on Thursday.

The union first balloted its members in June 2022, with numerous strikes and other industrial action taking place since.

Mick Whelan, Aslef’s general secretary, said: “Our pay deals at these companies ran out in 2019.

“Train drivers at these train operating companies have not had an increase in salary for five years.

“That is completely wrong. The employers – and the [UK] government – think we are going to give up and run away. They’re wrong”.

Great Western Railway said it will continue to operate limited services between Cardiff Central and Bristol Temple Meads, however all other GWR services have been cancelled.

It also warned services in the days following the strike could be affected.

The Rail Delivery Group, which represents train companies affected by the strikes, said last month: “This wholly unnecessary strike action called by the Aslef leadership will sadly disrupt customers and businesses once again, while further damaging the railway at a time when taxpayers are continuing to contribute an extra £54 million a week just to keep services running.

“We continue to seek a fair agreement with the ASLEF leadership which both rewards our people, gives our customers more reliable services and makes sure the railway isn’t taking more than its fair share from taxpayers.”
