Phyllis moved to Royal Oak Portal as she prepares to start her dig

By Tom Lawson

Less than 36 hours since the visit by the Mayor and Secretary of State for Transport on Tuesday Crossrail's first tunnel boring machine, Phyllis, has now been moved to the Royal Oak Portal site ahead of the start of tunnelling.

As you can see from the short time lapse sequence, she was placed on a self-propelled mobile trailer and moved to the top of the portal ramp, around 400 metres from its previous location at Westbourne Park. The Hampden Street footbridge was temporarily closed and carefully jacked-up to allow the tunnel boring machine to progress underneath.

Phyllis will now undergo final testing ahead of tunnelling commencing.

Once the TBM has progressed sufficiently into the tunnel, Ada, our second tunnel boring machine, will be moved towards the portal, undergo similar testing and then launched.

When Ada reaches Paddington, both machines will then progress forward through the Paddington station box to Bond Street and then onwards to Farringdon.
