A reduced train service between Essex and London is running this morning due to emergency engineering works.
Emergency work is taking place to repair a junction just outside London Liverpool Street, which has put several platforms at the station out of use.
As a result, there are numerous cancellations and delays taking place.
Trains have been replaced with a shuttle bus service between Braintree and Witham, which is expected to continue until about 3pm.
London Underground and c2c are accepting tickets on reasonable routes.
