Trains through Crystal Palace

Description

A fault with the signalling system at Crystal Palace means trains have to run at reduced speed on some lines.

Trains running to / from and through this station may be delayed by up to 15 minutes or diverted.

Disruption is expected until 18:00.

Customer advice:

Services running through Crystal Palace may be subject to delays of up to 15 minutes, or be diverted to run along a different route to normal. Services towards London Bridge and London Victoria are more likely to be affected.

You should leave at least 20 minutes extra to complete your journey.

Services which normally run from West Croydon to London Victoria may instead run via Selhurst. Diverted trains will not call at Norwood Junction, Crystal Palace, Gipsy Hill, West Norwood, or Streatham Hill.

As a result, you may need to travel on a different train to normal, or change trains at an intermediate station to complete your journey.

Your ticket will be accepted at no additional cost on the below:

• Alternative Southern services between Croydon, London Victoria and London Bridge

• London Buses between Croydon and central London

You should listen to announcements and check station screens while travelling for the latest information. You should check journey planners before you travel.

Can you tell me more about the incident?

Trains are likely to have some delays due to a fault with a signal in this area. In this case, the signal is unable to show the normal coloured light indications to drivers, and instead, it's showing a red light. This means drivers have to stop at the signal and gain verbal instructions to continue. Your journey will unfortunately take longer as a result.

Railway signals are designed to warn drivers that they have to stop because the system can't yet confirm that the route ahead is clear. In most places, the signalling system will show a green light, or aspect, when the track is clear for a long distance ahead, and drivers will then be shown one or two yellow lights to warn them when they are approaching a red signal. This means that they can anticipate the amount of braking that's required to stop before they reach another train or any form of problem on the line.

Signalling runs on "fail safe" principles, so if the signals can't step through the usual colours, they will instead show a more restrictive colour - for example, red instead of green. This means drivers will have to stop, but in fact, the route ahead may still be clear. This leads to delays.

The signalling system is maintained by Network Rail, and we're working closely with them to diagnose the fault and make sure it is fixed as quickly as possible.
