Delays of up to 60 minutes are expected between Stevenage and London Kings Cross due to a signalling problem between New Barnet and Alexandra Palace.
National Rail sent a message from its Twitter account at 6.12am saying the delays had occurred. They are currently still ongoing.
Network Rail apologises for any inconvenience caused.
