Train operator blames weather for travel problems
The wintry weather is being blamed for delays and cancellations on rail services in Essex, Norfolk and Suffolk.
A spokesman for both National Express East Anglia and c2c said services were subject to short-notice changes.
The operators were planning to operate "a scheduled timetable evening-peak service" on Friday.
Services are currently running on all routes and calling at all booked stations but cancellations and delays may still occur, a spokesman said.
All lines on the National Express East Anglia regional network were open and train services were operating to the advertised timetable wherever possible.
"Shuttle train services may operate between Southminster and Wickford, Witham and Braintree and Manningtree and Harwich Town in place of the normal scheduled timetable," the spokesman said.
The main National Express East Anglia lines link London with Norwich, Ipswich and Chelmsford.
Branch lines cover Cambridgeshire, Essex, Norfolk and Suffolk while c2c cover London to Southend and other parts of Essex.
"Passengers are also advised to allow extra time to make their journeys," the spokesman said.
