Multiple train journeys between Norwich and London will be badly affected today because of a 'major track fault'.

The engineering problem took place at London Liverpool Street station.

Greater Anglia said the fault would prevent trains from using some platforms, meaning alterations to some peak services.

Services which are impacted are:

?6am Norwich to Liverpool Street terminates at Colchester.

?7am Liverpool Street to Norwich has been cancelled

?7.05am Norwich to Liverpool Street terminates at Colchester

?8.30am Liverpool Street to Norwich starts at Colchester

?9.30am Liverpool Street to Norwich starts at Colchester

?2.30pm Norwich to Liverpool Street terminates at Stratford

?3pm Norwich to Liverpool Street terminates at Stratford

?3.30pm Norwich to Liverpool Street terminates at Stratford

?5pm Norwich to Liverpool Street terminates at Colchester

?5pm Liverpool Street to Norwich starts at Stratford

?5.30pm Liverpool Street to Norwich starts at Stratford

?7.30pm Liverpool Street to Norwich starts at Colchester

Plans for the Greater Anglia line were due to be finalised last night but some services on the routes from Norwich, Ipswich, Harwich, Clacton, Braintree, Colchester, Chelmsford, Southminster and Southend to London were expected to be affected.

Off peak services are scheduled to run as normal.

Ticket restrictions will be lifted and tickets from Great Eastern Main Line stations will also be valid on West Anglia services.

A Greater Anglia online spokesman apologised in advance for any inconvenience caused to customers and said Network Rail engineers are working to fix the fault as soon as possible.

Customers are advised to check the Greater Anglia website www.greateranglia.co.uk later for details of any service alterations.
