Commuters on First Capital Connect (FCC) services face delays this morning after a signalling problem on the track.
Currently there are delays on services between Stevenage and Kings Cross of about 10 minutes.
Trains between Welwyn Garden City and Moorgate are also affected by the problems.
A spokesman posted on the FCC website at 8.50am: “A signalling problem near Potters Bar is causing delays of up to 10 minutes between Stevenage and London Kings Cross / Moorgate.”
Network Rail tweeted (@networkrail) that engineers were on the way to fix the problem: “#PottersBar Engineers are en route to site to assess the problem.”
