Can you tell me more about the incident?

A train has developed a fault and is unable to move, blocking the line towards Clapham Junction from Watford Junction.

Operators are sending specialist engineers ("fitters") to the site to assess and fix the issue as quickly as possible. If needed, we may also arrange a rescue train to tow the faulty train to a depot.

While they work to move the train, Southern will try to divert other services if possible. This depends on available tracks and signalling options. Southern are working closely with Network Rail to minimise disruption and will update you as soon as they have more information.
