Two mega tunnel boring machines have arrived in Sydney
These two giant machines will be the first TBMs in the ground for Sydney Metro West
They will excavate from The Bays to Sydney Olympic Park, carving out a section of the 24km twin railway tunnels that will deliver fast and reliable metro services to Sydney's West
Fun fact: these tunnel boring machines include refurbished parts from the TBMs used on the Sydney Metro City and Southwest project
Heaviest pieces of the TBM are the front shield and gripper shield which weigh approximately 280 tonnes each
Once launched, the newly arrived TBMs will excavate an average of 200 metres per week
Each TBM weighs almost 1,300 tonnes, equivalent to three Boeing 747 jets
The cutterhead is approximately seven metres in diameter
There are 8 disc cutters per cutterhead, each more than 48 cm in diameter
These TBMs are 165 metres long, longer than two Airbus A380s
When Sydney Metro West opens in 2030 it will double rail capacity between Greater Parramatta and the Sydney CBD
46 metro stations by 2030
4 metro lines by 2030
113km new metro rail
