Passengers across the UK face further disruption on Friday and Saturday as the National Union of Rail, Maritime and Transport Workers (RMT) and Aslef stage additional industrial action.

Members of Aslef, the train drivers’ union, will walk out on Friday and will refuse to work overtime on Saturday.

Up to 20,000 RMT union members at 14 operators will also strike on Saturday as part of a long-running dispute over pay.

The strikes are expected to throw travel plans into chaos on the last weekend of the school holidays.

Aslef general secretary Mick Whelan said: “The government appears happy to let passengers, and businesses, suffer in the mistaken belief that they can bully us into submission.

“They don’t care about passengers, or Britain’s railway, but they will not break us.

“Train drivers at these companies have not had a pay rise for four years, since 2019, while inflation has rocketed.”

Aslef has walked out on 11 occasions, while the RMT has staged 33 days of industrial action during the ongoing dispute.
