It is one of eight TBMs that will shortly be transported to Tilbury, each weighing in at around 1,000 tonnes and around 140m long.
The machine will take two months to re-assemble at Westbourne Park, ahead of tunnelling commencing from Royal Oak in March.
To construct the 21km of twin-bore tunnel for Crossrail, the eight TBMs will carry out 10 individual tunnel drives.
Construction of the concrete segment factory for the western running tunnels between Royal Oak and Farringdon is now complete at Old Oak Common.
The plant will begin manufacturing over 70,000 segments for the western tunnels from January.
The five 6.2m diameter tunnels to be constructed are:
- Royal Oak to Farringdon west (Drive X) – length of drive approximately 6.2 km
- Limmo to Farringdon east (Drive Y) – length of drive approximately 8.3 km
- Stepney Green to Pudding Mill Lane (Drive Z) – length of drive approximately 2.7 km
- Limmo to Victoria Dock Portal (Drive G) – length of drive approximately 0.9 km
- Plumstead to North Woolwich (Drive H) – length of drive approximately 2.6 km
Chris Dulake, Crossrail’s chief engineer said: “The new Tunnelling and Underground Construction Academy has welcomed its first students and will train at least 3,500 people with the skills required to work below ground while the first of the tunnel segment manufacturing plants will shortly commence full operations.”
Following the launch of the first TBM a second tunnelling machine will be launched from Royal Oak a few weeks later.
The remaining TBMs will be then launched from Limmo Peninsula in the Royal Docks heading towards Farringdon in late 2012, from Pudding Mill Lane and Plumstead in 2013, and from Limmo Peninsula to Victoria Dock in 2014.
