At approximately 8.3 km in length, Limmo Peninsula to Farringdon was the longest of the five Crossrail tunnel drives. Two giant tunnelling machines, Elizabeth and Victoria, were launched in 2012 to drive westbound to Farringdon via Canary Wharf, Stepney Green shaft, Whitechapel and Liverpool Street at depths of up to 40 metres deep.
Crossrail’s eastern tunnelling machines, named Elizabeth and Victoria, were launched from the Limmo Peninsula site near Canning Town towards in late 2012 to create 8.3km (5.16 miles) of tunnels from east London to Farringdon – Crossrail’s longest tunnel section.
It took just over three years to construct the tunnels, with Elizabeth and Victoria successfully breaking through into Farringdon station in May 2015.
Elizabeth arrived at Farringdon on 9 May 2015 and sister machine Victoria successfully broke into Farringdon Crossrail station on 23 May at 5.30am. Victoria then constructed the remaining section of Crossrail tunnel as she progressed into Farringdon station, completing the job and linking all Crossrail tunnels.
Crossrail tunnelling ended on 26 May 2015 when TBM Victoria completed her journey.
