London train derailment: TfL London Overground and Southern Watford services face days of delays

Rail disruption is expected to last until later in the week after an engineering train derailed on the weekend.

National Rail said that during planned engineering works, an engineering train derailed between Shepherds Bush and Wembley Central.

Work to re-rail the train has been completed, but the derailment damaged the points and the overhead electric power lines, and additional repairs are required. This means the West London Line route is unable to be served.

The routes affected are the London Overground between Clapham Junction and Stratford, Southern between Clapham Junction and Watford Junction; between East Croydon and Watford Junction/Hemel Hempstead; and between Selhurst and Hemel Hempstead.

National Rail says trains running between the stations will be disrupted until 5am on Thursday January 25, after the incident was first reported in the early hours of Sunday.

London Overground disruption

On Tuesday morning, Transport for London (TfL) was reporting that there was no service between Willesden Junction and Shepherd's Bush.

The incident means the route between Stratford and Clapham Junction is disrupted. A shuttle train service is operating between Shepherds Bush and Clapham Junction.

National Rail said: "Customers are strongly advised to seek alternative onward travel - Local buses, London Buses and London Underground services are accepting London Overground tickets via any reasonable routes."

Southern rail disruption

National Rail advises passengers travelling to/from Watford Junction and Hemel Hempstead to use alternative routes and "leave at least 45 minutes of extra time".

Tickets are accepted on the London Underground and on buses, as well as on services operated by London Northwestern Railway, Thameslink, London Overground and Chiltern Railways.
