Following failure of the electricity supply between London Kings Cross and Stevenage the line towards London is now open. Trains may still be cancelled, delayed or revised.

Disruption is expected until 20:30.

Customer Advice:

Great Northern and Thameslink

Network Rail colleagues are investigating a power supply issue affecting some lines towards London from the Potters Bar area.   As a result, there will be no service towards London at the following stations:

• Hadley Wood
• Alexandra Palace
• Hornsey
• Harringay

If you are at these stations, you should travel back on yourself, to Potters Bar, to then take a London bound train. Alternatively, you can use local bus routes between Potters Bar and Finsbury Park, where your ticket will be accepted at no extra charge, to complete your journey.

Can you tell me more about the incident?

We will update you as we receive more information from our Network Rail colleagues.
