Following the official unveiling of 1,000 tonne Phyllis, Crossrail's first tunnel boring machine (TBM) 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.
The arrival of the TBM at the portal in mid-March allowed for remaining major works to get underway to support tunnelling.
