Whitehaven tunnel expected to be closed until spring next year
Rail replacement bus services are in operation to transport passengers
Passengers in Cumbria are being warned Whitehaven tunnel is expected to be closed until Spring 2026.
Network Rail says the extent of strengthening work needed means the tunnel cannot safely reopen until completion of comprehensive repairs.
It says planned track renewal specialist engineers have been working to deliver a lasting solution for the line.
The extent of the work needed means Bransty tunnel, between Whitehaven and Corkickle is expected to be closed until around Easter time.
Passengers can travel across much of the Cumbrian Coast Line, except through the circa 1km tunnel that takes trains through Whitehaven into Corkickle.
Rail replacement bus services are in operation to transport passengers between the seaside resorts while the work is ongoing.
Additional ground investigations will continue around the tunnel to build a complete picture of subsurface conditions.
The work forms part of broader infrastructure improvements designed to enhance reliability on this vital transport link serving Cumbrian coastal communities.
"really disappointing news"
Phil James, Network Rail’s North West route director, said: “The safety of passengers and staff is our number one priority and I understand that this is really disappointing news for passengers in this part of Cumbria.
"Our experts have spent a great deal of time examining the data and having it reviewed by peers in the industry.
"They all agree that this is the right thing to do while further investigation can be carried out and a specialist plan put in place.”
Matt Rice, Chief Operating Officer for Northern said: "We are sorry for the frustration that this disruption is causing, and we are working hard to keep customers moving whilst work takes place inside the tunnel.
"Trains are running to Whitehaven on the northern side of the tunnel, and we are now also running trains to Corkickle on the southern side.
"We'd like to remind customers to plan ahead and check before you travel".
