Network Rail has agreed a £2.3bn funding package with Crossrail for new infrastructure enhancements and surface works.
Agreement on the final anticipated cost will ensure works are completed to enable Crossrail services to Maidenhead, Heathrow, Abbey Wood and Shenfield.
The deal marks one of the largest commercial contracts in the company’s ten-year history and marks a further significant milestone in the delivery of the project.
Network Rail will carry out modifications at 27 surface stations, provision of power for the new rolling stock including overhead lines, and the building of a new, larger flyover at Stockley in Hillingdon to enable Crossrail services to operate to Heathrow.
Network Rail Infrastructure Projects managing director Simon Kirby said: “Network Rail’s combined roles of operating and upgrading the existing railway mean that we are uniquely placed to deliver the above ground elements of this world-class project.
“We’ve spent two years working with our customer, Crossrail Limited, and we are confident that we have the right plan, expertise and resources. We and our supply partners are now completely focused on efficient delivery for passengers and our customer.”
Crossrail’s surface director Matthew White said: “To enable Crossrail services to operate, Network Rail will be undertaking a multi-billion upgrade of the rail network with major improvements planned for the Great Eastern and Great Western main lines including better stations, electrification, new and improved signalling and the integration of the new Crossrail tunnels with the existing railway.”
