The biggest rail strike for more than three decades threatens to cause chaos across the country over some of the biggest events of the summer.
One union boss says the industrial action over three days later this month will “shut down the system”.
Tens of thousands of RMT union members will walk out over three key issues: pay, compulsory redundancies and safety concerns.
Sky News takes a look at the train lines and events that will be affected – including the return of the biggest music festival in the world for the first time since 2019, international sports fixtures and meetings with Commonwealth heads of state.
When is the strike planned?
The walkouts by the RMT union are planned for 21, 23 and 25 June.
Up to 50,000 of its members across Network Rail, 13 train operators and on the London Underground will strike on 21 June in the “biggest outbreak of industrial action in the UK since 1989”.
An estimated 40,000 rail workers – excluding staff on the Tube – will strike on 23 and 25 June, the union said.
Services are likely to be affected throughout the week because of the knock-on effects on trains and crews.
The strike dates follow ballots that ended last month.
