Damage to the overhead wires between Stevenage and Hitchin means all lines are blocked. As a result, trains running between these stations may be cancelled, delayed or revised.

Disruption is expected until the end of the day.

Customer advice:

Great Northern and Thameslink

All lines are closed between Stevenage and Hitchin due to damage to the overhead electric wires. This incident will cause severe disruption to Thameslink and Great Northern services, as well as long-distance trains in this area.

We don't have an estimate for the delays, as the route is closed. We recommend you avoid travelling at present.

We will arrange ticket acceptance on alternative routes shortly. These options will not cover all journeys.

If you're waiting on a train which is delayed between stations:

If your train is delayed between stations, please remain where you are and listen to announcements, or speak to staff for further information. We'll get you moving as soon as possible. We're aware of your location, and our teams will be doing everything they can to help you continue your journey.

Please don't leave the train unless you are asked to do so. Other trains may still be moving in the area, and the track is also a very hazardous environment.
