RAIL users will face long delays this morning (Friday) on the First Capital Connect commuter line going through Welwyn Hatfield and Potters Bar.

Due to signalling issues and overhead power cables at New Barnet the line between Peterborough, Cambridge and London King’s Cross has been suspended.

This includes stations at Welwyn Garden City, Hatfield, Brookmans Park and Potters Bar.

Trains are being redirected via Hertford North and passengers are being asked to use the bus or tube by both First Capital Connect and Network Rail.

Network Rail tweeted to say it is on site and trying to fix the problems.

A spokesman said: “Track and Signalling & Telecoms engineers are on site working to resolve the problem ASAP.”

Neither company could say when normal service would resume.
