I had front row seats as Elizabeth, one of our 900 tonne mega Tunnel Boring Machines, emerged from the ground after digging 2.1km of tunnel for the North West Rail Link. Gladys looked pretty happy after Elizabeth emerged! And Gladys should be proud, because she is delivering the goods as we #rebuildnsw. Was great to celebrate todays milestone, and I captured this video to give you a #bairdseyeview (sorry, pretty bad dad-joke there...) This project is so far $300 Million UNDER budget, and 4 of these tunnel boring machines are hard at work digging Australias longest railway tunnels for a rail link that will see 8 new stations built and a train arrive every 4 minutes. So far, Elizabeth has: • Excavated more than 206,000 tonnes of crushed rock, both sandstone and shale • Installed more than 7,300 concrete segments to line the new rail tunnel • Been home to 85 workers, including tunnellers, maintenance crews, geologists, surveyors and engineers, who combined have spent more than 25,000 hours underground and • Had 40 hardened steel cutters on her cutter head replaced, worn down from the harsh forces of cutting the Sydney sandstone and shale. Elizabeth has no time for a holiday though. She will be back in the ground real soon, setting off again towards Showground Station.
