Can you tell me more about the incident?

There has been 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, crew will gather details and report this to the Fleet teams. If possible, the defect will be fixed promptly, and the train will get on its way. The 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, we'll send our specialist engineers to site, known as "fitters". Southern 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, Southern then monitor progress updates and ensure that the railway can be reopened as promptly as possible.

Until the defective train can be moved, attempts will be made to try and 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. Southern work with Network Rail's controllers to decide how many more trains can be sent through the area, and if this isn't possible, alternative solutions will be looked into to help you continue your journey.
