Freeing up space on the East Coast Main Line

We’re enabling more passenger trains to be able to run on the East Coast Main Line (ECML) by building a new two-track railway line. At just over 3km in length, the ‘dive-under’ will run under the ECML just north of Peterborough at Werrington Junction and will allow high-speed trains to pass over the Great Northern Great Eastern Line (GNGE).

The existing crossing movement causes constraints as freight trains, and the occasional passenger service, on the GNGE route currently have to pass over the high-speed East Coast lines. Werrington Grade Separation will remove this conflict.

Work began in autumn 2018 and is expected to take three years to complete.

What work are we doing?

North of the newly extended Cock Lane footbridge, the Stamford Lines will be widened to the west to create four tracks. The central pair of tracks will then dive into a new underpass, below the ECML, and rise to meet the GNGE line approximately 600 metres after Lincoln Road.

To get a real sense of how the proposed dive-under will look, watch the footage of the completed design.

A site office and compound for the work has been established to the west of the ECML, off Stirling Way, and to the east of the ECML off Hurn Road. These offices and compounds will be in place for the duration of the project.

Background

The plans were approved by the Secretary of State in August 2018 following a successful application for a Transport and Works Act Order, which involved extensive public consultation and engagement with stakeholders. Our engagement with stakeholders, including the local community, will continue throughout the work.

Latest news – rolling on the river

We’ve been digging a new river to make way for track realignment.

The new river replaces Brook Drain North and has been designed to help with local flood issues.

To tackle the unusual task, we have worked closely with the Environment Agency and specialist geotechnical and landscape designers to design the river diversion.

The new river is 840 metres long and four metres deep. Designed to hold a larger volume of water than the previous river, the watercourse is less likely to flood and impact passengers.

The design also features riffles – shallow sections of water – and side pools, where aquatic wildlife can take refuge during storm surges. Soft bank ledges have also been installed to help vegetation to grow.

We used clay excavated from the site to backfill the old river, reducing the need for it to be relocated or for new materials to be brought in. Working alongside a zoologist with a specialism in moths, we have also helped create a new habitat for rare Four Spotted moths that were found living on the riverbank.

Keeping you informed

This project is one of the largest on the ECML and involves a lot of construction activity that has the potential to be disruptive to residents and businesses at specific points in time. We will write to everyone affected in advance of this type of work.

To help keep people informed, we are holding a series of community drop-in sessions. Members of the project team will be on hand to answer any questions on the scheme:

This year, 14:00 – 18:00 at the Loxley Centre, just off David’s Lane, Peterborough, PE4 5BW
