The works on this project were undertaken by Sword from February 2013 to March 2014 under contracts to Carillion appointed by Network Rail as the principal contractor in the fitting out and tie-in of the railway systems for Canal Tunnels, to connect the East Coast Main Line to the existing Thameslink system at St Pancras.
Works carried out by Sword included:-
- Installation of a new track slab
- Installing new walkways
- Installing new exits to the 2 tunnels
Approximately 5000m3 of concrete was placed which was challenging given the enclosed nature and restricted width of the tunnel.
