A blockage on the Great Northern line is causing cancellation and delays for trains from Welwyn Garden City, Stevenage and Royston.
All lines are blocked between Moorgate and Finsbury Park due to a train coming to a standstill at Old Street.
Services are being diverted into London King's Cross and restarted from Finsbury Park.
Tickets will be accepted on the London Underground between Moorgate, Finsbury Park and King's Cross.
