Video and images: Crossrail makes tunnelling breakthroughs

Crossrail has achieved a fortnight of construction milestones with three tunnel boring machine breakthroughs and the completion of western train tunnels.

The 42km tunnelling marathon is now 70 per cent complete with over 30km of new rail tunnel under London now constructed.


  • Crossrail’s western tunnels completed as TBM Ada reaches her final destination at Farringdon on 24 January
  • TBM Sophia completed Crossrail’s first tunnel beneath the Thames, arriving at the North Woolwich Portal on 29 January
  • TBM Jessica completed her tunnelling journey from Pudding Mill Lane and broke through into one of Europe’s largest mined caverns beneath Stepney Green on 3 February
  • Tunnelling machine Elizabeth made a spectacular entrance into the new Crossrail station at Whitechapel on 20 January on her journey from Limmo Peninsula to Farringdon. Her sister machine Victoria also broke through into Stepney Green on 30 January.
