Description
Lines have now reopened following a fault with the signalling system between Royston and Cambridge. However, whilst service recovers, trains running between these stations will be delayed by up to 60 minutes, cancelled or revised.
Major disruption is expected until 15:00.
A visual disruption map video is available.
Customer advice:
A limited Thameslink and Great Northern service will now run in both directions between Royston and Cambridge
The route has reopened, following a complete failure of the signalling system at Foxton earlier today.
However, a large number of trains and crews are no longer in the correct places, and we expect it will take until mid-afternoon to get back to a normal timetable.
Please check journey planning tools before you go to the station, and be aware that alternative journey options are extremely limited.
Your journey is still likely to take at least 60 minutes longer than usual.
