TransPennine Express (TPE) has warned customers that trains may still be delayed or cancelled at short notice until 12:00.

It says people should travel as planned but check whether their journey has been affected by the disruption.

It adds that people can use Thursday’s tickets on Friday at no extra cost. It has also relaxed ticket restrictions, allowing people to travel on any TPE train on their booked route.

TPE says customers delayed by more than 15 minutes may be able to claim compensation for their journey.

I’ve just come through Birmingham New Street, one of the busiest train stations outside London - and one of those briefly affected by yesterday’s power failure.

But it’s business as usual here this morning, as commuters and holidaymakers make their way through the turnstiles.

Ozzy the mechanical bull, a sculpture named after Black Sabbath frontman Ozzy Osbourne, is overseeing a near-perfect timetable.

In fact, there’s barely any disruption showing on the big departures board above me. Just a smidgen of red. Let’s hope nothing changes.

National Rail has updated its travel advice, saying disruption in the north-west of England and the Greater Manchester area is expected until 12:00.

Earlier, it warned that the disruption would last until late on Friday.

Disruption between Newport and Cardiff Central in south Wales is still expected to last until at least the end of the day.

A transport journalist has warned that trains and crews will be out of position across the country today, causing disruption.

Andy Bowes-Roden, deputy editor at Modern Railways magazine, tells BBC Radio 5 Live there will be "quite a lot of disruption this morning easing throughout the day".

"Hopefully by rush hour the service will be back to normal, but it won't be until tomorrow morning that this will be sorted," he adds.

"As rail passengers, we are lucky. We have protections and the railways are obliged to get us where they promise to get us," he says. "But there will be an awful lot of refunds."

During the worst of the chaos yesterday, staff here at Manchester Piccadilly say they tried not to leave anyone stranded and provided drinks and snacks for passengers whose journeys had to be abandoned.

There's a sense of relief here this morning that the electrical failure that caused the problem is now apparently fixed, and things are slowly returning to normal today.

Although the knock-on effects of the disruption are continuing to services, the worst of it is over.

The problem started just after 14:00 BST yesterday when there was a power failure at a rail operating centre in Manchester - effectively the nerve centre which controls signalling across a lot of the north-west.

It meant trains just weren't able to keep running safely. Services were held in many places, others were cancelled, and signalling lights turned to red for safety.

The disruption spread across north-west England, also affecting services from Birmingham and London.

It was a very frustrating and potentially very expensive day for passengers.

The knock-on effect is continuing today. The advice is to check before you leave home.

• Which rail lines are impacted?

Travel expert Simon Calder has been speaking to BBC Breakfast from London Euston Station.

He says there've been cancellations already this morning, including a train a few minutes ago to Manchester and another to Liverpool.

Asked about the power failure which caused the disruption, he says lots of questions are going to be asked about the resilience of the system.

"This is clearly a piece of critical national infrastructure," he says, and it "weakens confidence in the rail network at a time when they desperately need to get more people travelling by train".

Going into the weekend, things could get "even trickier for a number of passengers" with strikes at St Pancras and also engineering works in some places, he says, adding: "Good luck everybody!"

Passengers are still showing up at Manchester Piccadilly this morning and taking a look at departure boards, lots of people still have holidays to get to.

Many services are running but a scan down the list also shows a number of cancellations.

Rail workers say yesterday's power problems are now fixed, but the scale of the disruption meant that lots of trains ended up in the wrong places overnight and it’s going to take a while to get things back in the correct locations for services to run properly.

As well as disruption in north-west England, National Rail says there'll be major disruption until at least the end of the day between Newport and Cardiff Central in south Wales.

It'll affect these routes:

• CrossCountry between Nottingham and Cardiff Central
• Great Western Railway between London Paddington and Swansea / Carmarthen, and also between Taunton / Exeter St Davids / Portsmouth Harbour and Cardiff Central
• Transport for Wales between Manchester Piccadilly and Pembroke Dock / Milford Haven / Fishguard Harbour, and between Holyhead / Chester / Cheltenham Spa and Cardiff Central, and also between Newport and Ebbw Vale Town

A fire near the tracks between Cardiff Central and Newport last week caused the disruption.

Trains across north-west England and the Greater Manchester area "will be cancelled, severely delayed or revised" today, National Rail says. Here are some details on which operators are impacted.

• Northern: Customers are being advised not to travel before 10:00. Northern says it will not be running any services into Manchester Victoria or between Preston, Bolton, Wigan, Liverpool and Manchester "for the remainder of the day"
• Avanti West Coast: If your train is cancelled, your ticket is valid on one of the two services immediately before your booked train or one of the two immediately after
• East Midlands Railway: Tickets dated for yesterday that were not used are valid for today
• TransPennine Express: The company "strongly advises" travellers to check their journey before setting out as it says "services may be delayed or cancelled at short notice"
• Transport for Wales: Buses will run between Liverpool Lime Street and Chester until the end of the day and tickets can be used for no extra cost on Merseyrail services between the stops. Transport for Wales says customers should allow extra time for journeys
• London Northwestern Railway & CrossCountry: Trains are not expected to be impacted

Major rail disruption is expected to continue in north-west England and the Greater Manchester area until late on Friday, National Rail is warning.

Trains will be severely delayed, cancelled or revised across the network, and trains that can run may only travel along parts of their routes, the rail network says.

Yesterday, train passengers were left stranded for hours after a power failure in Manchester impacted a railway communications centre.

Costs to avert the trouble were high, with some opting to get home via taxi as others booked hotels.

Engineers are working hard to fix the issue but a number of trains being in the impacted location mean disruption will continue on Friday morning, National Rail says.

To avoid getting caught out, be sure to check your travel on the National Rail journey planner, external before you go.

Passengers across England have faced major disruption today after a power failure affected a rail operating centre in Manchester.

The outage occurred just before 14:00 BST, Network Rail said, with disruption expected to spill over into tomorrow morning.

Our transport correspondent Katy Austin said the disruption caused a "ripple effect", with some trains outside the area directly affected - including the Midlands - also impacted.

The advice to travellers has been to check before making a journey.

We've been hearing from people whose plans have been disrupted by delays and cancellations.

We heard from one passenger whose train - from Deansgate to Leyland - had a "controlled evacuation" after it was brought to a halt while still on the tracks, leaving them stranded.

"Costly, inconvenient... frustrating," is how Chris from Edinburgh described the disruption. He was in Manchester for work and said he may have to stay the night because he had "no idea" how to get home.

We've also heard from people facing taxi rides "costing a fortune" just to get home.

We're ending our live coverage now but you can read more in our story here. You can also check whether you're entitled to compensation.

As we just reported, Network Rail earlier warned "a wartime bomb near the railway between Tamworth and Burton-on-Trent" was blocking all lines between the two stations.

In an update on X, it says that the disruption caused by the bomb has now ended.

We've been hearing how today's major train disruption has been affecting you this afternoon.

Chris, from Edinburgh, tells us he's stuck in Manchester after travelling down for business. He says he's "no idea" how he'll get home and will likely try and find a hotel for the night - something he calls "costly, inconvenient... frustrating".

Also trying to make the journey from Manchester to Edinburgh is Becky, a teacher from Bristol. Her synchronised swimming team are likely to miss a performance in Edinburgh this evening due to the disruption, and says "it's all kicking off".

Matt and his partner Sarah were also stuck in Manchester after flying back from Gibraltar earlier today. After their train home was cancelled, they decided to book an Uber instead, which the couple say is "costing a fortune".

But it's not just in Manchester where services have been disrupted.

At Birmingham New Street, Bradley Black is struggling to head back north to pick his daughter up from nursery after a work trip. "I’m trying to ring the nursery and get a late pick-up, pay some extra cash to keep her there for a couple of hours," he says.

Meanwhile Sarah Nelson hasn't been able to even make it to work due to the disruption, and now says it's "going to be a nightmare" trying to get back home to Blackpool.

It's not just the power outage causing disruption to trains in the Midlands.

National Rail says "a wartime bomb near the railway between Tamworth and Burton-on-Trent means all lines are blocked between these stations".

It added that trains would be cancelled, revised or delayed by up to an hour. Disruption had been expected to last until 19:30 BST.

As of 19:10 BST, National Rail says that at least eight rail operators remain affected by the disruption that has seen widespread cancellations and delays across much of England.

Avanti West Coast says its trains between London Euston and Manchester Piccadilly may be delayed, cancelled or diverted.

CrossCountry advised that servies can now run from Manchester, but says some services may still have "knock-on delays".

East Midlands Railway says to not travel between Sheffield and Liverpool Lime Street, adding that there remains disruption between Liverpool and Nottingham/Norwich.

London Northwestern Railway says rail replacement busses are in operation between Liverpool Lime Street and Crewe, and between Crewe and Birmingham New Street.

Lumo's 13:19 train from London Euston to Stirling is running 42 minutes late after being delayed at Preston.

Northern says do not travel, as its services are unable to run on all routes in the north west and Greater Manchester.

TransPennine Express also advises against travel on its services as there are cancellations on all routes.

Transport for Wales says services to Manchester Picadilly - and between Liverpool Lime Street - may be cancelled or delayed.

However, other major rail companies operating through and near the affected region, including LNER and West Midlands Railway, have reported good service.

Tickets for many of the above operators can be used on trains run by other rail companies - these details are listed on each operator's website.

As we've been reporting, Transport for Greater Manchester says the outage occurred at the Manchester Rail Operating Centre (ROC) after a power supply failure in the wider Ardwick area.

That signalling centre was opened in July 2014.

It was one of 12 ROCs, which Network Rail said at the time "will eventually manage the entire rail network across Britain, replacing more than 800 signal boxes and other operational locations currently used to control trains".

Railway lines have slowly been added to the ROCs workload, with Network Rail adding at the time of its opening that "over the next 20 years all of the railway in the north west of England will be controlled from the ROC".

Jo Hooper was half an hour into her rail journey to Manchester from Grimsby when passengers were given some bad news.

"We were told the service was cancelled and terminated at Sheffield," says Jo, who was heading to Manchester to head off on a weekend break with her daughter.

After waiting for more than an hour for a rail replacement bus in Sheffield, Jo says she's now "slowly heading to Manchester" and should arrive only two-and-a-half hours later than planned.

"Happy days," she says. "I've been reading other passenger stories and feel I’ve got off lightly."
