A broken down train between Hatfield Peveral and Chelmsford means some lines towards London are blocked. As a result, trains may be cancelled, delayed by up to 30 minutes or revised.
Disruption is expected until 13:30.
Customer advice:
The 11:35 Colchester Town to London Liverpool Street service has come to a stand due to loss of power between the train and the overhead electric wires.
The train will have to be rescued as a result and the line will be blocked whilst the faulty unit is being assisted away from the line. Train services may be delayed, altered or cancelled at short notice.
Advance purchase tickets holders will be allowed to travel on earlier or later trains if their booked service is cancelled.
