This is one of a number of Crossrail’s Tunnel Boring Machines (TBMs). According to tunnelling tradition, a TBM cannot start work until it is given a name and, back in February 2012, one of the first was named Phyllis after our founder. Around 150 meters long and 1000 tonnes in weight the Phyllis TBM was launched on the 4th of May 2012 from the Royal Oak Portal and completed the 6.8km tunnel drive to Farringdon on the 8th October 2013. The Crossrail route will run over 100km from Reading and Heathrow in the west, through new tunnels under central London to Shenfield and Abbey Wood in the east. The first section of the Elizabeth line opens for service in May 2017 and will be fully open in December 2019.
