Elizabeth line innovations: moving the industry forward

Skills and experience gained are already benefiting other projects in UK and internationally, in Sydney, Vancouver and San Jose.

Throughout our involvement with the project, our engineers have authored in-depth technical papers to further the knowledge and understanding of specific areas of a megaproject. These are published on Crossrail’s Learning Legacy website, a collation and dissemination of good practice, lessons learned, and innovation aimed at raising industry standards.
