BCS / Carillion – West Ealing Carriage Sidings.

ESL was contracted to undertake the OLE detailed design of the sidings.
This was a complex project as it involved numerous multidisciplinary interfaces within the sidings themselves. In addition to this, the power supply on the main lines was in the process of being upgraded to an autotransformer system with a new ATF wire. This introduced a further interface, with electrical clearances required to be considered at different stages of completion of the adjoining project. A further challenge was the requirement to install new equipment compliant to modern standards within the new sidings, which needed to tie in to the existing Mk3 equipment on the main lines. This involved non-standard design arrangements with some modelling required to verify compliance.
The whole scheme design development was undertaken in a 3D environment using a federated BIM model hosted within the ProjectWise platform to comply with the requirements of CrossRail’s engineering management systems.
Undertaking the design in this way eased the identification and rectification of clash detection through the IDC process.

Project Description

As part of the ongoing upgrade of the route west of Paddington, new Stabling facilities were required for First Great Western Electric Trains at West Ealing Sidings. This project, part of the wider CrossRail scheme, involved re-aligning the p-way within the sidings, installing new walkways to facilitate cleaning and the installation of CETs, the construction of a new two storey driver training facility and electrifying the sidings roads to accommodate the new electric trains.
