THE Sydney Metro West – Western Tunnelling Package (WTP) has recently achieved significant milestones, with the arrival of two mega autonomous tunnel boring machines (TBMs) at Sydney Olympic Park to complete the first two tunnel entries for the future station.
The deployment of these autonomous TBMs on the Metro project marks a historic first for Australia.
