The possession will be handed back over the weekend for a light loco to 'route prove' and stock balancing to happen before services start Monday. Damaged unit is being roaded out in the next couple of weeks.

Rail passengers are being thanked for their patience after a train derailed in Grange-over-Sands on Friday 22 March 2024.

One month on, services are running again on the Furness line between Lancaster and Barrow-in-Furness.

Network Rail engineers have been working around the clock to restore the railway at Grange-over-Sands after a Northern train left the tracks.

A void in the ground was found about 150m away from the derailed train.

More than 8100 hours of work has taken place to get the railway restored so trains can run again.

Engineers removed 400 tonnes of spoil from the embankments, and installed almost 84 tonnes of new materials to repair the damage at the location.

Phil James, Network Rail’s North West route director, said: “I’d like to thank passengers for their patience while we worked tirelessly to get the railway back up and running after it was severely damaged by the void and train derailment.

“This has been a very complex recovery and repair job. We're continuing to work with the Rail Accident Investigation Branch on the investigation into what caused the derailment, but we're really glad we've been able to work quickly to get the railway fixed.

“I’m pleased that the line is open again for passengers on the busy Furness line.”

Network Rail have been working closely with train operator, Northern, to keep passengers on the move during the closure.

Craig Harrop, regional director for Northern in the North West, said: “We’d like to thank our customers for their patience while these important repairs to the rail infrastructure have been carried out by Network Rail. We’re very pleased to be able to resume rail services on the Furness Line and re-connect our customers with the rest of our network.”

Network Rail is working with the Rail Accident Investigation Branch (RAIB) to identify the cause of the void and derailment.

NR facts and figures in these announcements often make no sense.
What does this tell me:
“Engineers removed 400 tonnes of spoil from the embankments, and installed almost 84 tonnes of new materials to repair the damage at the location.”
So have they taken over 300 tonnes away and just not replaced that volume?

I don't know what they've done here, but modern embankments are often made of lighter materials than before - I remember (20 years ago) watching them do the one over the Manchester Ship Canal and a load of it was basically a form of polystyrene block!

That was very specific and isn't the general case and can be quite expensive. Although it was fascinating to read about.

If the line reopens on monday it's objectively good news.

Well, I was kinda hoping I'd get my £90 return to Ulverston tomorrow refunded through delay repay as with the last 3 times (due to the bus taking an hour longer), but yes, it is good news :lol:

Always wondered what will happen if a trainload of petrol derails and spills on that embankment! The whole embankment could just melt away!

Weren't they craning in box culvert sections - that would dramatically reduce the weight of the embankment. (Or was that just someone's bright idea - if you accept that the golf course will become a tidal/salt marsh again?)

Polystyrene blocks have been used in road embankments too, where fuel spillage is a more likely event. The main risk mitigation is to wrap the polystyrene in an impermeable membrane to protect it from spills. I've never heard a report of such an embankment failing.

I very much doubt any has been used at Grange though, it's usually only used where an embankment has to be built over a deep layer of soft ground.

Yes my comment was a bit tongue in cheek and I would expect the polystyrene to be protected. However, I would expect the (unlikely) derailment of a fuel train involving split tanks to release considerable amounts of fuel. For example, Llangennech involved a spill of 446,000 litres, fortunately not petrol.

The photo in Post #357 suggests repair was by completely conventional methods.

I’m sure you’re right about fitting box culvert sections being no more than wibble.

It's an excellent example of chinese whispers. The suggestion was made by posters on this board that a long-term solution would be to build a proper bridge. That somehow became 'they are going to be putting in box sections' and now has become full-circle to 'wibble' again. There has been no suggestion from anybody at Network Rail that they would be doing anything other than putting the line back as was.

AFAIK the first suggestion of craning in Box Culvert Sections came from @AndrewE in post #435. The previous discussions didn't mention any specific construction methods. There are mentions of Culverts in posts 97 & 98 but no mention of any particular type. Posts #311, 313 and 315 refer to a 'proper bridge'.

Wibbling? Short of reading back over 400 odd comments ... was time available / taken to consider whether there would be advantage in some kind of box culvert (with appropriate one-way valves to allow seaward-only passage of water otherwise lying against the embankment?). I guess that could be considered/ done at a later date. Good to see service restored, which is important.

In this type of situation they will normally reinstate something similar to what was there before rather than attempting an enhancement. Reinstatement needs little or no design work so can start more quickly on site, and importantly doesn't need so many permissions and agreements. Creating a new culvert would change the water flows which are obviously rather sensitive, and would need various discussions to get it agreed.

I read in the local press that the line from Barrow northwards towards Bootle was closed this morning due to a landslip, but has been reopened since.

A driver reported a potential landslip. On further investigation, it was sandy deposits that had come from a newly dug badger sett.
