Northbound trains travelling between Hitchin and Arlesey have been disrupted due to a signalling fault.

Delays – which were reported by train operating company Great Northern at about 3.15pm – are expected to last until about 5pm while engineers remain on the scene.

Passengers travelling northbound to Arlesey are advised to change at Biggleswade for a southbound service back to Arlesey. Those travelling north from Arlesey are advised to travel south to Hitchin and change for a northbound service towards Peterborough.

A Great Northern spokesman said: “There is a reported fault with the signalling system and Network Rail, who own and maintain the equipment have staff attending to effect repairs.

“While this is ongoing, our services may be delayed or subject to alteration. Once the fault is repaired, we will be working to restore the train service to the normal timetable as quickly as possible.

“We are sorry for the delay to your journey today.”
