"Crossrail’s first giant tunnel boring machine (TBM), Phyllis, has broken ground at Royal Oak to construct the first section of tunnel between Royal Oak and Farringdon.
"Keith Sibley, Crossrail Area Director West said:
"Tunnelling for Crossrail has now commenced. Phyllis is now beginning to slowly disappear below ground, and will steadily ramp up to the planned average tunnelling rate of around 100 metres a week."
"Following the official unveiling of 1,000 tonne Phyllis, Crossrail’s first tunnel boring machine travelled 400 metres to Royal Oak Portal, including under Hampden Street footbridge which was jacked up to allow the 7.1 metre diameter machine underneath."
