The 13 stations on the route, from Maidenhead in Berkshire to Acton Main Line in London, will be upgraded ahead of the introduction of Crossrail services in 2018.
Aecom’s design brief includes improvements such as platform extensions to allow longer trains, step-free access at most stations and building refurbishment.
Several bridges near stations on the route will also be redesigned to allow for over-head electrical cables.
“Aecom is delighted to have been selected to support Network Rail in delivering this section of the high-profile Crossrail scheme,” said Aecom’s project director John Crosfield. “Our team has the range of skills required to meet the challenging programme in a multidisciplinary rail environment and is committed to providing the project with robust design solutions."
