Morgan Sindall team completes 11,000-tonne rail tunnel push

An 11,000 tonne curved concrete box has been pushed under the East Coast Main Line near Peterborough, in what is being hailed as a first for UK engineering. Over nine days between 16th and 24th January 2021 the huge concrete box was pushed under the East Coast Main Line railway.

The prefabricated structure forms a new rail underpass at Werrington, north of Peterborough, to enable slower moving freight trains to dive underneath the passenger route and use an adjacent line northwards.

Time-lapse video footage shows the 155-metre curved concrete box tunnel being pushed into place at just 1500 mm per hour using four hydraulic jacks.
