A fault with the signalling system at Roydon means trains have to run at reduced speed on all lines. Asa result, trains running between Cheshunt and Bishops Stortford may be cancelled, delayed by up to 25 minutes or revised.

Disruption is expected until 17:30.

Customer advice:

Network Rail technicians have identified a defective cable to be the cause of the fault, and are now in the process of repairing this. Estimates for when repairs will be completed are by 16:00, but this is subject to change.

Routes directly affected;

• Stansted Express between London Liverpool Street and Stansted Airport
• London Liverpool Street - Cambridge North
• Stratford - Bishops Stortford

Service Impact

Trains are having to run at a slower and safer speed through the area in both directions, which is causing them to be delayed. To mitigate the delay, some trains may have amended calling patterns.
