Weather hits trains through Norfolk, Essex and Suffolk
Rail services have been hit by weather-related cancellations, delays, changes in train sizes and equipment failures.
National Express East Anglia services on the London line through Norfolk, Suffolk and Essex were disrupted by points problems at Witham in Essex.
This will affect services already hit by earlier failures to several trains.
Services are expected to return to normal during the day as repairs are made to faulty equipment but there may be more cancellations.
