Signalling problems are causing delays for commuters travelling through Tottenham Hale this morning.
Greater Anglia Trains say the problems between Hackney Downs and London Liverpool Street mean fewer trains are able to run on all lines.
Services running though Tottenham Hale, Northumberland Park, Seven Sisters, Bruce Grove, White Hart Lane and Silver Street are running with delays, with some trains being cancelled.
Tickets are being accepted on some bus routes and Underground trains.
