Crossrail, known as the Elizabeth Line, is one of the most significant infrastructure projects ever undertaken in the UK. Crossrail will bring an extra 1.5 million people to within 45 minutes of central London, link key employment, business and leisure hubs and serve 200 million people per year — improving journey times and easing congestion.

Covering over 60 miles (100 kilometres (km)) from Maidenhead and Heathrow Airport in the west of London to Shenfield and Abbey Wood in the east, Crossrail will traverse the city via a 13-mile (21-km) twin-bore tunnel connected to London’s underground system. It will stop at 41 stations, and includes 10 newly built stations and 30 station upgrades.

AECOM has supported the project in various ways since the early 1990s, including route selection, preliminary and detailed design. As part of the Transcend joint venture, alongside CH2M Hill and The Nichols Group, AECOM works as a programmme partner, supplying strategic management services to help Crossrail deliver. As the venture lead, AECOM works within a wholly integrated client programme management team, providing programme and project management, programme reporting, procurement, engineering management, assurance and industry partner management services.  

Developed by TfL and Network Rail, Crossrail 2 is a new proposed railway that will link key growth areas in the north east and south west of London, stopping at central London locations, boosting connectivity, and supporting economic growth.
