New Cross Gate LOCIP Depot

The scope of this project included minor civils, P-Way, ETE (third rail) and OLE to enable re-modelling of the existing depot layout including the supply of safety critical staff for the project.

Civil Engineering
Driver walkways, OLE bases, cable management routes & temporary hop-ups.

Permanent Way
Relocation of buffer stops and stripping out existing track to allow service diversions. Extension of the wheel lathe and heavy cleaning building, including installation of a new bogey turntable.

The scope also included the installation of 28nr IBJs to accommodate the signalling upgrade and a new CV40 turnout. Slab track was installed within the maintenance shed and outside.

Electrification
To facilitate the Permanent Way and Civils scope, modifications were required to both the OLE and Third Rail including the movement of conductor rail for walkway installation and extension of the OLE to the carriage wash road and headshunt.
