A train line has been thrown into chaos as a "system issue" is causing major disruption to services.
Train operator TransPennine Express has issued a "do not travel" alert for Wednesday due to the problem.
Passengers have turned up at stations across the region to discover that dozens of trains have been cancelled unexpectedly.
With just four days to go until Christmas, many people will find their plans to get home for the holidays complicated or made impossible by the issue.
The cancellations this morning will be particularly frustrating for passengers as rail workers aren't striking and it should've been a relatively rare day of good services.

"Transpennine Express are a serious contributing factor to my chronic stress," Laura Williams wrote on Twitter, alongside a screenshot of a departure board showing cancelled train after cancelled train.
"Almost every train has been cancelled at the last minute this morning. New timetable clearly does not work.
"Hours without a train service is no longer a forgivable rare occurrence."
Several people claimed that the rail operator had cancelled more than one hundred trains this morning.
The company's customer service and operations director Kathryn O'Brien said: "Due to a significant rostering system issue, today we are experiencing a high level of unplanned cancellations and disruption across our network.
"We know this will have a significant impact on customers travelling with us today and sincerely apologise for any disruption caused.
"We are working hard internally and with our system provider to resolve the situation as soon as possible.
"We are doing all we can to keep customers on the move but while problems persist, we advise customers not to travel and to seek alternative means of transport."
The company has been receiving a lot of criticism in recent weeks and months by passengers tired of the patchy service.
Almost a third of TransPennine Express train services were cancelled on a “dreadful” first full day of its new winter timetable, which was launched nine days ago.
It was meant to add hundreds of extra trains to the network, including three services an hour to and from Manchester to London on Avanti West Coast.
The rail operator cancelled 115 trains in full or in part, amounting to about 32% of planned services on December 12, the Guardian reported.
TransPennine has previously blamed a combination of problems, such as high levels of train crew sickness and a training backlog, for causing prolonged disruption.
It has also been hit by workers not volunteering to do paid overtime on rest days and infrastructure faults.
The disruption comes as Brits are already facing 18 days of strikes affecting railways and airports.
TransPennine Express routes will be one of the operators impacted by strike action by RMT union members from December 24 to December 27.
On Christmas Eve, services will end much earlier than planned and customers are advised only to travel if absolutely essential.
Anyone planning to make journeys on December 24 should aim to do so before midday, with final service of the day expected to be no later than 3pm.
