Delays and service alterations remain on the railway this morning due to continuing bridge repairs.

The underbridge, which carries the railway over a road between Witham and Hatfield Peverel, has been receiving attention from Network Rail engineers since the beginning of the week.

Damage to the structure, the responsibility of the state-owned infrastructure company, was reported on Sunday morning after a ballast cleaner train caused masonry on the bridge to crumble.

The unit is in operation overnight at weekends to improve the track’s foundations as part of a £170million mainline upgrade.

Speed restrictions to ensure safety are now in place around the bridge as engineers carry out emergency repair work, with disruption expected to last until 2am on Sunday.

Trains, including passenger services run by Abellio Greater Anglia, are limited to travelling at either 20mph or 40mph over the bridge making journeys a few minutes longer than usual.

Some trains serving Suffolk will either be delayed while travelling through the affected area, terminated at alternative stations or cancelled completely.

A full list of alterations, along with a delay repay policy, can be found on the Greater Anglia website.
