Travellers from Norfolk and Suffolk are advised by National Express East Anglia to use services through Cambridge.

Engineers worked through the night to repair the cables but only one track is passable on the line at Ingatestone.

Jonathan Denby, from National Express, said he had no idea when the line would be fully functioning again.

The overhead wires have been damaged between Chelmsford and Shenfield and it is hoped repairs will be completed for a normal service on Wednesday 11 June.

Many services are affected in Essex and train shuttle services will operate between Harwich and Colchester and between Braintree and Witham.

Lowestoft and Peterborough services will start and terminate at Ipswich.

First Capital Connect will accept National Express ticket holders.

A normal service will operate on the Metro/Southend and Southminster lines.

Network Rail has been urged by two councils to start improving the Norwich to London line (link below.)

Norfolk and Suffolk county councils have also written to the Transport Secretary Ruth Kelly about recent disruption to services.

The councils are calling for work to modernise the overhead power lines, some of which date back to the 1940s, to be speeded up.

Network Rail was unavailable to comment on the letter the councils have sent.

Adrian Gunson, from Norfolk County Council and the chairman of the Norfolk Rail Alliance, said there was growing concern that the age and condition of overhead lines near Chelmsford were putting reliability at risk.

Overhead lines are due to be replaced by 2012 but the councils want the work completed earlier.

In the letter, also sent to Ms Kelly, the councils have called for work on signalling to be brought forward, more upgrading of cross-country routes and high maintenance standards.

The two county councils have agreed to ask all their MPs for support over the issue.
