As part of the Crossrail West Outer Track Infrastructure Works project, a 73 mile (117km) new railway line in London, Network Rail built a new bridge over the line at Stoke Poges, near Slough. The new bridge accommodates overhead cables needed to introduce greener and more reliable electric trains. The original Horlicks Bridge, along with many others along the route, was not high enough to allow room for the overhead electric cables, so needed replacing.

We were contacted by Balfour Beatty Rail Limited to provide a temporary bridging solution to support existing services during the reconstruction of the Horlicks Bridge at Stoke Poges near Slough, Berkshire. Site restrictions in this busy area presented a challenge with limited space to pre-build the structure.
We provided a temporary bridge spanning 50m. The Mabey Universal Vehicle Bridge standard components were used to create an 11 bay reinforced box bridge. The bridge provided a 2.4m wide platform allowing for services to be laid across. The design of the bridge had a support load of 5kN/m to allow for the services plus pedestrian loading for access.
The structure used standard bridge panels as bracing and to provide support for the decking minimising cost and build time. The bridge was supported on 2 No. 3m x 3m Mat 125 towers, 5m high. Using the MU bridging system in reinforced box configuration allowed pre construction of the structure in the minimum time prior to the lift in.
A large 750Te capacity crane was successfully used to lift the bridge into position over the 4 track section of the line with less than 3 hours in which to lift it into position. Stiffness of the structure was critical and had to be kept to a minimum due to the delicate nature of the multiple services that are carried on the structure and their limited clearance over the railway deflections.
We’re delighted to have been involved in this part of the Crossrail project. It’s a key project for Network Rail and will significantly enhance public transport in London and the South East. Working alongside Balfour Beatty Rail Ltd, Mabey Hire’s temporary bridging expertise will allow for significant improvements to be made to the rail services in the Slough area.
Our engineered solutions range from standard designs to major projects, through to emergencies. We can also offer an end-to-end service from design and supply through to installation and removal.
We can work with you from initial concept temporary works design through to project completion, across all aspects of temporary works.
No matter how large or complex the project, we can help. It's what our major project teams do every day!
