Structural Case Studies

Reinforcing Historic Railway Architecture

As part of the W12 Freight Gauging programme, the retaining walls and supporting masonry arches on the approach to Chorley Tunnel were identified as requiring alterations to allow the running of larger freight traffic. The scheme included the removal of the existing track, the installation of a temporary propping solution (designed by Stobart Rail Engineering) to support the existing retaining walls, the careful removal of the historic masonry Flying Arches in one piece for careful storage for future reinstatement, installation of ground anchors, new 6ft drainage and trench sheets. Subsequently the track and its formation were replaced.

The works were undertaken in a six week blockade and were successfully handed back on time.
