Another Cross River Rail Tunnel and Stations TBM achievement. TBM Else has broken through at Northern Portal!
The Northern Portal marks the end of TBM Else’s tunnelling journey. This is where she will be dismantled and removed from the tunnel and where one day, trains will enter and exit Cross River Rail’s twin tunnels.
It’s been quite the journey for TBM Else, excavating around 3.8km underneath Brisbane, and we cannot thank the team enough for their efforts in making these project achievements possible.
TBM Else was named after trailblazing engineer Else Shepherd AM and just like her namesake the mega machine has made ground-breaking progress, completing the full tunnelling journey underneath Brisbane in under a year!
There’s just one more TBM breakthrough to go before the tunnels are fully excavated!
