What is the work at Werrington for and what benefits does it deliver?
The project at Werrington forms part of the wider East Coast Upgrade Programme.
A new tunnel, located just North of Peterborough, will remove constraints to the timetable caused by slower freight trains crossing over the high-speed East Coast lines at Werrington Junction.
This new ‘dive under’ will enable the new two track railway to run underneath the East Coast Main Line, separating it from any high speed passenger traffic.
