On the 16.01.2019 Sydney Metro’s third mega TBM started digging the 6.2 km of tunnel from Chatswood to the edge of Sydney Harbour at Blues Point. This marks the next stage in delivering the new 31km metro twin tunnels below the centre of Sydney and deep under Sydney Harbour.   The TBM has been named after Wendy Schreiber, a volunteer at Bear Cottage – the only children’s hospice in NSW and long standing charity partner for the Sydney Metro tunnelling contractor John Holland CPB Ghella. TBM Wendy joins TBMs Nancy and Mum Shirl, launched last year and are now tunnelling from Marrickville towards the CBD (City Business District). So far, TBMs Nancy and Mum Shirl have excavated 1.3 kilometres of tunnel and 114,000 tonnes of crushed rock from Marrickville on the 8.1 kilometre journey to Barangaroo. With two more machines due to start work this year, the borers will build 31km of Sydney Metro tunnels between Marrickville and Chatswood, including the first rail tunnels under Sydney Harbour.
