Members of the Rail, Maritime and Transport union (RMT) at 14 train operators will walk out, crippling services across the country. Passengers are warned to check before they travel.
No trains were running on any London Underground lines this morning due to action by drivers, leaving commuters to desperately find alternative transport, with many queuing and packing onto buses.
The militant RMT union has threatened to carry on striking until next summer as another 24-hour walkout cripples the rail network today with tens of thousands of workers now expected to WFH instead.
In a clear act of defiance to Sir Keir Starmer, Shadow Transport Secretary Sam Tarry turned up at Euston station in solidarity with the 40,000 RMT members on strike today.
