If you are travelling now you will need to allow at least 90 minutes of extra time.

Thameslink, Southern and Gatwick Express services across the whole network have been subject to alterations, cancellations and significant delays due to a number of incidents:

  • A fault with the signalling system in the Purley area is causing significant disruption to services running across the network this morning

  • We've also had a fault with the signalling system in the Hatfield area which has now been fixed

If you are travelling to/from London Bridge or London Victoria, to the coastal routes:

If you are travelling to/from Gatwick Airport:

You will need to use an alternative route for your journey. Services to/from Gatwick Airport will be significantly reduced meaning you may need to make your own arrangements for travel.

Can you tell me more about the incident?

Trains travelling through the Purley area are experiencing delays, alterations and cancellations due to a signal fault.

Railway signals warn drivers when they need to stop. Normally, a green light means the track is clear, while yellow signals warn of a red light ahead.

Signalling works on "fail-safe" principles. If a signal cannot change properly, it defaults to a more restrictive setting, causing trains to slow down even if the track is clear.

Network Rail maintains the system, and Southern, Thames and Gatwick Express are working with them to fix the fault as quickly as possible. In the meantime, we are monitoring services and doing our best to keep to the timetable.

.Compensation:

You may be entitled to compensation if you experience a delay in completing your journey today. Please keep your train ticket and make a note of your journey, as both will be required to support any claim.
