All train lines are blocked between London King’s Cross and Alexandra Palace due to a damaged overhead electric wire causing major disruption to all services in and out of London.

Passengers from Herts, Beds and Cambs will be affected and tickets are being accepted from King’s Cross and Moorgate to board reasonable London Underground routes. London Overground, Greater Anglia and Thameslink are also accepting tickets via reasonable routes.

Delays are expected until 7pm.
