There is major disruption between Barrow and Lancaster after a Northern train derailed.
The train came off the track at around 6am on Friday, March 22 near Grange-over Sands.
Four passengers and four members of staff were safely evacuated from the train, but the railway will be closed for some time in both directions.
There is a limited bus replacement service but passengers are advised to avoid travelling if at all possible.
An investigation has been launched by the Rail Accident Investigation Branch and inspectors will have to examine the scene before the train can be removed and the railway repaired.
Engineers have discovered an unusual hole in the ground has opened around 150m away from the derailment.
Network Rail said the team was working hard to investigate the cause. Ground conditions at the site are extremely wet and has advised people to stay away from the location to allow responders to carry out their work safely.
Chris Pye, Network Rail’s North West route infrastructure director, said: “All lines through this area remain blocked.
“We’re really sorry for the disruption. Passengers are encouraged to please check with Northern or National Rail Enquiries for the latest travel information including alternative travel arrangements.”
Craig Harrop, regional director for Northern, said: “We are focusing on supporting colleagues and customers who were involved in the incident and on minimising the disruption this incident will cause to other services. We’re working closely with Network Rail and others to understand more about what happened.
“No trains are running between Barrow-in-Furness and Lancaster and there will be significant disruption to our services in this area. Customers should look on our website or speak to a member of our team for more information.”
Northern added that it was aware of a block on the A590 which was also causing delays to traffic.
