Train lines between Ely and Downham Market have reopened after a signalling problem caused disruption throughout the evening.
Engineers from Network Rail are currently attending the affected area to carry out repairs, and train services running through both stations have been delayed by up to 45 minutes.
Once the fault is repaired, Great Northern will be working to restore the train service to the normal timetable as quickly as possible.
Replacement bus services have been offered to affected passengers between Ely and King's Lynn.
You may be entitled to compensation if you experience a delay in completing your journey today. Please keep your train ticket and make a note of your journey, as both will be required to support any claim.
