A fault on a train between Peterborough and St Neots, means some lines towards London Kings Cross are blocked. As a result, trains running between Peterborough and Stevenage may be cancelled or delayed.

Disruption is expected until 19:00.

Customer advice:

Great Northern / Thameslink

Thameslink services heading South from Peterborough will be delayed. At present, the train that is blocking the line has developed the same fault again, so services will continue to be blocked from leaving Peterborough. This is affecting long distance trains in the area as well.

Your journey will be extended by up to 35 minutes.

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 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.

Can you tell me more about the incident?

We've had a report of a fault on a train, and this is now causing delays to other services travelling through this area.

Normally, when a fault on a train occurs, crews will gather details and report this to their fleet teams. If possible, the defect will be fixed promptly, and we'll get the train on the way. These initial steps are designed to take around 10 minutes.

However, sometimes the fault cannot be fixed in this time frame. In this case, wherever possible, the train will be taken out of use and sent to a depot. This does take additional time, as the crew will need to make sure that everyone's managed to leave the train.

If this can't be done either, specialist engineers will be sent to the site, known as "fitters". We have fitters based in key locations around the network, 24 hours a day, and they are able to attend anywhere on our routes. Once they are on site, we'll then monitor progress updates and ensure that the railway can be reopened as promptly as possible.

Until the defective train can be moved, we will try to find a way to get other trains around the issue. This depends how many lines are available, and whether the signalling equipment is set up to allow trains to be routed around the problem. This is more often the case on our major routes, but not always. We'll work with Network Rail's controllers to decide how many more trains can be sent through the area, and if this isn't possible, we'll see what alternative solutions are available to help you continue your journey.
