East Anglia’s rail services are facing serious disruption this week because of the heavy snowfall predicted over the next few days.

On Tuesday and Wednesday rail operator Greater Anglia is planning to run emergency services so it can concentrate on keeping main lines free.

There will be no services from Ipswich to Lowestoft and Felixstowe, or from Colchester to Colchester Town. There will be shuttle services only on the Harwich, Clacton, Walton, and Sudbury branches.

And there will be reduced, and slower, services on the main line between the region and London and on cross-country services from Ipswich to Cambridge and Peterborough. All services will stop running from 10pm on Monday, Tuesday and Wednesday evenings.

A spokeswoman for Greater Anglia said the changes had been made with Network Rail to try to ensure that some service was maintained on the main lines. The situation is being kept under review.
