A fault with the signalling system between Stevenage and Peterborough means that trains have to run at reduced speed on all lines. As a result, trains may be delayed by up to 30 minutes, cancelled or revised.
Disruption is expected until 14:00.
Thameslink and Great Northern Customer Advice:
You may be delayed by up to 30 minutes between Huntingdon and Peterborough. Some services from Peterborough towards St Pancras may need to be altered at short notice, and may run non-stop on part of their journey.

Can you tell me more about the incident?
A signalling problem is affecting both lines between Huntingdon and Peterborough at present, meaning trains have to run at a reduced speed in both directions. This is causing a queue of trains to build, delaying services running to and from Peterborough.
The fault has been confirmed as a 'Track Circuit Failure', and this means the signalling system is unable to automatically verify if the next section of track past the affected signal is clear.
The rail network is designed so that if a signal stops working, trains will stop before they reach it. Whilst this issue is ongoing, train crew will stop at the affected signal and contact the signalling centre to confirm their location. At this point the signaller will verbally authorise the driver to continue towards the next signal. This process adds time to every train's journey, which means services can experience short delays.
