Handover and Assurance on the Elizabeth line


Crossrail Ltd plans to bring the Elizabeth line into passenger service as soon as practically possibly in the first half of 2022.

A key challenge that remains is the volume of handover assurance and documentation that must be completed to enable the railway to be brought into passenger operation.

The assurance regime for the Elizabeth line is complex and requires the integration of 500,000 individual railway assets such as public address systems, smoke alarms and CCTV cameras which must undergo a series of safety checks before each one is issued with a safety document.

Nearly 200,000 documents need to be completed as part of the assurance and handover process and safety certification for the Elizabeth line.


There are millions of assets that needed to be tested and assured for the Elizabeth line. Our Engineering Assurance team explain this extensive and complicated handover process underway for all 30 stations, shafts, portals and railway systems.


Crossrail is working with the Elizabeth line service and infrastructure teams to get operations and maintenance staff familiarised with the new railway. Our network operations team explain the detailed training underway.
