Track Cross River Rail TBMs
Monday 17th May 2021 – Media Release
Cross River Rail TBMs can now be tracked in real-time. I know, exciting right?
They have recently launched a new online tool through their website that allows the public to follow the project’s TBMs as they dig the twin tunnels in real-time beneath Brisbane.
TBMs Else and Merle – both weighing in at 1350-tonnes – were excavating the project’s twin tunnels from Woolloongabba north towards Albert Street.
Meanwhile, two 115-tonne roadheaders were excavating the tunnels in the opposite direction from Woolloongabba towards Boggo Road.
“With TBM Else and TBM Merle on their way north, and the project’s roadheaders excavating south, Cross River Rail’s year of tunnelling is well and truly underway,” Cross River Rail Delivery Authority CEO Graeme Newton said.
The Tracker showed the project’s TBMs and roadheaders as they excavated the project’s 5.9 kilometres of twin tunnels, including how far they had already travelled.
This is a great tool for the public to see all the work and construction happening underground, we are otherwise we are quite oblivious of the sheer scale of work taking place beneath our feet.
Each of the TBMs is equipped with trackers and sensors which fed technical information to the project team in real-time.
The TBMs would reach Albert Street mid-year, before continuing to Roma Street and finally emerging at the project’s northern portal at Normanby before the end of 2021.
