Millions of Brits are set for travel chaos starting today as they face being caught up in a massive train strike that is the biggest in a generation after last ditch talks failed to reach agreement.
Up and down the country people will be affected with only a fifth of services running and half of lines closed due to the dispute over pay, jobs and conditions - with all sides blaming each other for the lack of progress.
Much of Britain will have no passenger trains throughout the day, including most of Scotland and Wales, the whole of Cornwall and Dorset, and places such as Chester, Hull, Lincoln and Worcester.
Instead, services will primarily be restricted to main lines, and even those will only be open between 7.30am and 6.30pm.
Thousands of members of the Rail, Maritime and Transport (RMT) union at Network Rail and 13 train operators will walk out on Tuesday, Thursday and Saturday.
Those operators not involved in the industrial action will still suffer from disruption due to Network Rail signallers going on strike.
London Underground workers will also walk out today.
Reports that Labour has banned its frontbenchers from picket lines, in a memo leaked to Politics Home, has led to fury from the unions.
Sharon Graham, general secretary of Unite, said: "The Labour Party was founded by the trade unions and we expect Labour MPs to defend workers, by words and by actions."
Also affected by the strike are pupils and parents who are being urged to make an alternative plan for getting to school for A-level and GCSE exams on Tuesday and Thursday.
Motorists are warned to expect a surge in traffic as train passengers switch to road transport.
The AA predicted that the worst affected roads are likely to be main motorway arteries, as well as rural and suburban areas.
About half of Great Western Railway's trains due to serve Castle Cary in Somerset, carrying revellers to the Glastonbury Festival between Wednesday and Friday, are cancelled.
Prime Minister Boris Johnson is expected to say ahead of a Cabinet meeting today that unions are "harming the very people they claim to be helping".
He is set to accuse unions of "driving away commuters who ultimately support the jobs of rail workers", while also hitting businesses across the country.
"Too high demands on pay will also make it incredibly difficult to bring to an end the current challenges facing families around the world with rising costs of living," he will state.
"Now is the time to come to a sensible compromise for the good of the British people and the rail workforce."
RMT general secretary Mick Lynch said Network Rail had offered a 2% pay rise with the possibility of a further 1% later dependent on efficiency savings.
He told BBC's Newsnight that Network Rail had "escalated" the dispute during Monday's talks.
He said: "They have issued me a letter saying that there are going to be redundancies starting from July 1.
"So rather than trying to come to an agreement in this dispute, they've escalated it by giving us formal notice of redundancy amongst our Network Rail members."
He warned the dispute could continue for months, adding: "It is clear that the Tory Government, after slashing £4 billion of funding from National Rail and Transport for London, has now actively prevented a settlement to this dispute.
"The rail companies have now proposed pay rates that are massively under the relevant rates of inflation, coming on top of the pay freezes of the past few years.
"At the behest of the Government, companies are also seeking to implement thousands of job cuts and have failed to give any guarantee against compulsory redundancies."
The Department for Transport disputed Mr Lynch's clams, adding that it has cost taxpayers about £600 per household to keep the railway running during the coronavirus pandemic.
