TRAIN services have been disrupted this evening because of signalling problems.

Some lines are blocked because of the problem at Gidea Park station in Romford with trains unable to travel through the station at the moment.

Train services running through the station may be cancelled or delated by up to 30 minutes at short notice.

Network Rail engineers are working to resolve the problem but some trains from London Liverpool Street to Shenfield will be diverted via another line and trains to Southend Victoria and Colchester may also be delayed.
