Train users from Hitchin and across lines from north Herts into London are strongly advised to not to travel after damage to overhead electric wires between London and Finsbury Park resulted in all lines being blocked.

Trains are currently unable to run between London Kings Cross / London St Pancras International / Moorgate and Stevenage.

Trains will be subject to delays and cancellations. Some trains will start / terminate at different locations to normal. Journey times may be extended by up to 90 minutes with disruption expected until the end of service.

The problems came after Network Rail staff identified a 'de-wirement' in the Copenhagen Tunnels just outside Kings Cross. Due to this no services will be able to depart from London Kings Cross, London Moorgate or St Pancras towards Stevenage and Hitchin via Cambridge and Peterborough.

Alternative Travel Information

Rail replacement buses are being organised, but these will take several hours to get fully in place. When this is set up there will be reduced capacity due to Covid mitigations. So please only use these if your journey is essential.
