Severe disruption on the Norwich to London train services.
Commuters are facing severe disruption today as no train from Norwich to London will leave until past 3.30pm.
The 1.30pm, 2.30pm and 3.30pm services were and have been cancelled due to power line damage near London.
Network rail say the cause of the damage is unknown but not suspicious. Power had to be cut while engineers fixed the problem and their solution to freeing up the timetable was to cancel trains.
A National Express East Anglia spokesman said: 'Train services suffered delays and cancellations from 11am because of overhead power line defect in Forest Gate. This was rectified by early afternoon. We apologise to passengers for any inconvenience caused.'
