Major rail delays after signalling fault

A signalling fault has caused major delays to rail services.

National Rail said the Thameslink services between London Kings Cross and Cambridge, going through Hertfordshire and using the Great Northern route, affecting Cambridge, Ely and King's Lynn, were disrupted.

It said an earlier "complete failure" of the signalling system at Foxton, Cambridgeshire, meant no services could run between Royston, Hertfordshire and Cambridge, but the lines have now reopened after engineers carried out repairs.

Disruption is expected until 15:00 GMT as "a large number of trains and crews are no longer in the correct places".

Thameslink said while services recover "trains running between these stations will be delayed by up to 30 minutes, cancelled or revised".

Most Thameslink and Great Northern services are now running in both directions between Royston and Cambridge.

Great Northern said services on the King's Lynn route were still affected as "a few trains and crews are still out of position on the network".

"It is expected it will take until mid-afternoon to get back to our full timetable, especially on the route between London Kings Cross and Ely/King's Lynn," it said in a statement.
