Rail InfrastructureProject Overview
Due to subsidence issues, Cairn Cross replaced 137m length of the Road 16 rail pit walls and associated works.
The Challenge
Due to subsidence issues, approximately sixty metres of permanent way rail track and maintenance pit were closed due to safety concerns. Cairn Cross took the procession of the shed from the North East entrance through to the end of the new pit construction to excavate the pit and reinstate 137 metres of new rail tracks and maintenance pits in the depot.
The Solution
Cairn Cross temporarily removed the interior access platforms to gain safe access to remove 137 metres of subsided track and pit. The rail was removed and stored for reuse, and the pit walls and walkways were excavated. Once demolished, new reinforced steel and formwork was lifted into place, and concrete poured and struck. Once the new pit walls, walkways and track was implemented, we carried out the lighting and associated works.
The Result
The new depot allows for the maximum efficiency of maintenance work to be carried out throughout the entire length of the shed. New safety stairwells and lighting within the pit improve the overall safety of the depot.
