Latest Crossrail update – October 2021

Trial Running

Crossrail continues to make progress with trial running taking place with 12 trains per hour to test reliability and flush out any issues and identify bugs to fix. The aim at this final complex stage is to ensure the trains are completely safe to run before opening.

Update October: Crossrail have now commissioned the ELR100 software following a two-week blockade during which timetabled train movements as part of Trial Running were paused across the railway. Trial Running will resume in the coming days, and the performance of the software will be assessed to determine the commencement of Trial Operations. Further reliability fixes have been identified and these will be accommodated during the Christmas period.

During the recent blockade the tunnel ventilation system was also updated, with final testing and software adjustments due to be undertaken at Christmas to get the system to a level that can safely support passenger service.

The final railway integration tests to ensure all the components work together seamlessly have now been completed with the exception of the final integration of Bond Street. These tests covered the tunnel ventilation system, trains, software, signalling, platform screen doors and power systems.

Trial Operations

These operations include exercises to prove the system is ready for passengers. These will test the whole system to check everything works effectively. The end of trial operations marks the final step before passengers can use the service from the first half of 2022.


There has been no significant injury reported on the project for five consecutive periods; there have been mior slips and trips. Learnings will be taken from these incidents to improve safety.

Central section progress

Central section stations need to reach specific stages of completion in order for the programme to move into trail operations phase. Most of these stations are now with TfL, except Canary Wharf, Abbey Wood and Bond Street.

Operational readiness

Train software upgrades are being rolled out to ensure a high performing passenger service.

Network rail

The network rail is also updating in preparation for the Elizabeth lines. Better, more spacious entrances and ticket halls are being built, with additional accessibility from lifts and bridges.
