Commuters are experiencing cancellations and delays between Liverpool Street and Shenfield due to signalling problems at Maryland Station.
So far this morning five trains have been cancelled on the route, and more may disrupt commuters travelling between Shenfield and Gidea Park, though the problems have been fixed by Network Rail engineers and delays are expected to shorten.
All Greater Anglia tickets will be accepted on TfL bus routes 25 and 86 between Romford and Liverpool Street.
