Queue management is back in force here at St Pancras.

I was standing on the concourse and there was a sudden surge of people as staff wanted to move the hundreds of passengers who are trying to get on to the few services that are running.

The queue is now snaking around one end of the station - something that anyone who has used Eurostar on a busy day will be familiar with.

Some more good news for the passengers here at St Pancras - more services have appeared on the departure board, including the 19:01 to Paris and the 19:34 to Brussels.

I've also seen the first service appear on the arrivals board. A service from Paris is expected at 19:35.

This is what the departure board currently says at the Eurostar terminal of St Pancras.

The 17:31 service to Paris has now fully boarded, with the 18:01 service currently welcoming passengers aboard.

Later trains are also due to start boarding over the next hour or so.

Rob, who shared these pictures with us, has just boarded his LeShuttle train from Calais with his wife and two children after more than a six-hour wait.

However, Rob - who has been stuck in Calais since 10:30 GMT this morning - still has the long drive up to South Yorkshire waiting for him after he disembarks in Kent.

“We are both working tomorrow morning, so will have to continue the journey in one go tonight," he says.

Dina Motashaw is currently travelling on the 15:04 Eurostar to Brussels, the first service to resume since the Channel Tunnel was partially reopened. But it took her more than 10 hours to reach this point.

The 21-year-old student, from Croydon, arrived at St Pancras at 06:00 GMT this morning to catch the 07:04 service to Lille, northern France, where she plans to visit her boyfriend for New Year's Eve.

Dina boarded that train, but it was sent back to London after it got stuck for four hours.

She then had to wait in "massive" queues to return to the St Pancras waiting area. "It was absolute chaos," she says.

When the 15:04 was announced, passengers with tickets for that train were let on first, followed by people who were on the earliest trains of the day.

"I had to shout at people saying I was on that first train," she says. "I fought so hard for that and I am really emotional right now. Honestly, it was really hard, there were so many people."

Despite the station staff urging her to hurry, the carriage was mostly empty when the service started moving around 16:00 - almost nine hours after Dina was meant to depart.

"Hopefully there's no more delays and there's no more problems, because I just want to get to Lille," she tells me from the train.

We've been reporting on scenes of chaos at St Pancras today as passengers travelling to France via the Channel Tunnel saw their journeys cancelled or severely delayed.

However, two musicians have been trying to keep spirits up, with one playing the piano that has been installed at the station while another plays the violin.

Some Eurostar services have resumed after the closure of the Channel Tunnel brought a day of disruption, but customers are still being advised to make alternative travel arrangements. Here’s the latest:

• There has been a resumption of some Eurostar services, starting with the 15:04 train from London to Brussels - which departed shortly after 16:00. Some other services are expected to follow
• But customers are still being urged not to travel. If you’ve been affected, here’s advice on what to do instead
• The Department for Transport says disruption in the Channel Tunnel is "likely for the remainder of the day” while faulty overhead cables are repaired
• The LeShuttle service, which takes road vehicles on trains across the Channel, has resumed "very gradually”, but significant delays are expected
• Meanwhile, traffic on the M20 near the LeShuttle terminal in Folkestone has now eased
• Many customers have been forced to make alternative travel plans after their trains were cancelled, with some now unable to attend New Year’s Eve celebrations
• There were also delays in Paris, with large crowds of passengers at Gare du Nord

Only one line in the Channel Tunnel is available for trains to run on, Eurostar says in a statement to the BBC.

That's due to ongoing overhead power supply issues, which Eurostar says will lead to continued delays and longer journey times than usual this evening.

The train company points passengers to its earlier advice on their options for compensation, adding that it will also cover reasonable expenses for those stranded due to the disruption.

Eurostar says the compensation includes:

• Hotel accommodation up to £150 / €170 per room, per night (or a suitable three-star hotel where availability is limited)
• Taxi costs up to £50 / €60 per journey
• Food and drink expenses up to £35 / €40 per person, per day

A train driver for Eurostar has provided us with this image that they received today in a WhatsApp group for current and former Eurostar drivers.

The driver says the image appears to show that overhead electrical cables have been brought down in one of the two passenger rail tunnels, which "would have affected the other tunnel too".

"There's more than just one cable involved. There's the contact wire, then there are 'droppers' which hold the wire in place," they add.

Getlink, who operates the Channel Tunnel, has been approached for comment.

• The BBC has verified the identity of the driver, but the image does not have the necessary data attached to confirm when or where it was taken

• Update at 13:35 GMT on 31 December: A Getlink spokesperson says: "This photo was provided by an unofficial source and not authenticated by Eurotunnel. It has not been established that there is a link between it and the incident on the catenary yesterday in the Channel Tunnel."

I'm talking to a passenger on the 15:04 service to Brussels - the first Eurostar service to resume since the Channel Tunnel was reopened.

She tells me the train has just started moving.

"It's such a relief, I'm just hoping there's no more problems," she says.

We heard earlier from a British traveller in Paris about the price of flights going up.

I've been keeping an eye on the availability of flights in both directions between London and Paris.

About 30 minutes ago, Skyscanner - a website which aggregates flights from across different airlines - wasn't showing me any direct flights from London to Paris.

The only options were journeys making stops elsewhere in Europe first, with estimated journey times of as long as 25 hours.

I then refreshed the website, and one direct flight to Paris today was showing: an 18:40 departure from Gatwick to Charles de Gaulle airport.

Another refresh 10 minutes later and the flight was gone again, then it reappeared again at the cost of an eye-watering £465.

There are some direct flights to Paris tomorrow, although they again cost in the hundreds. The cheaper options again include stopovers, adding many hours onto journey times.

The situation is much the same for flights going from Paris to London.

Of course, this may all change again. I'll keep checking throughout the afternoon.

I'm watching more people join the queue to board the 15:04 Brussels service, and the departure board that earlier read "cancelled, cancelled, cancelled" has updated.

It now says the 17:31 and 18:01 to Paris will open an hour before departure. Some good news for the passengers who were booked on those services.

The 18:04 to Amsterdam is also on the board.

After previously warning of 45-minute delays on the M20 near the LeShuttle terminal in Folkestone, National Highways says traffic has now eased in the area.

The congestion was focused around the eastbound exit slip road to the Channel Tunnel vehicle terminal.

The LeShuttle service, which takes road vehicles on trains across the Channel, has resumed "very gradually" and is operating in both directions on one track with "significant delays", Eurotunnel says.

"Additional shuttles will be added in the evening and until tomorrow morning," the operator says in a statement.

Denyse owns the Benett Arms in Semley, Wiltshire, and is trying to get back in time for New Year's Eve tomorrow.

She is in Paris for a holiday with her wife, Deborah, to celebrate Deborah's birthday.

They were due to get the Eurostar back this morning from Paris Gare Du Nord, but have been stuck in the station for hours.

"Lots of people were talking about what they were going to do. Flight prices were going up and up as we were talking, the last price I saw was for £1,000," she adds.

"We can’t book a ticket for tomorrow. So maybe we’ll catch a train to Calais or fly to Bournemouth or Bristol, but our car is in London. We’ll have a glass of wine and make a plan."

A few minutes ago we also received an update from the Department for Transport, which says that disruption through the Channel Tunnel is "likely for the remainder of the day". This is despite services resuming at St Pancras International.

"Eurotunnel is working with operators to resume some services while repairs to overhead electrical cables in the Channel Tunnel are ongoing, however significant disruption is likely for the remainder of the day," a spokesperson says.

They add that the department is "working with Eurotunnel, Eurostar and the Kent and Medway Resilience Forum (KMRF) to minimise disruption for passengers" and encourage passengers to check with their operator for updates and advice.

Eurostar has just announced the 15:04 service to Brussels is boarding.

The man with the loudspeaker is surrounded.

Suddenly there is a lot more movement as people move to get into the queue. I heard one woman say "we're going".

Dozens of holiday goers are still looking desperately on at the empty Eurostar departures area at St Pancras International.

In the past hour, I have seen several people in tears while many passengers remain absorbed in their phones as they try to keep their New Year’s plans alive.

Many tourists have been here for hours - some since very early this morning - as they try and book flights, ferries and hotels to continue their journeys.

But there may be some hope.

We've heard an announcement that the Channel Tunnel has partially reopened, with Eurostar advising services will resume. But as the overhead power issue remains, the operator is also urging passengers to postpone their journeys to a later date.

The Eurostar departure area at St Pancras is cordoned off empty, where you would normally expect to see hundreds of people queuing to get through security and board trains.

The passengers who are here are all on their mobile phones, trying to re-book for another service, hopefully tomorrow.

You have to feel for people. One couple who'd been booked on a service to Paris today are here from the US and it's their 25th wedding anniversary.

The company that operates the Channel Tunnel says train traffic will "gradually resume" this afternoon. Eurostar says some of its services will also resume, but it still strongly advises passengers to postpone their journeys to a different date.

If the disruption impacts you, here's what Eurostar is advising:

• Exchange your booking for free to travel in the same travel class but at a different time or date
• Cancel your booking and claim an e-voucher - you'll have 12 months from the date of your disrupted journey to redeem it on Eurostar's website
• Cancel your booking and get a refund - this will be for the ticket value, but won't include any booking fees

Eurostar says passengers will have three months from the date of the ticket to claim their preferred option.
