Tunnelling

19/04/2021

Our first tunnel boring machine, the Lady Eileen Hudson, is on the move. Named after an important Snowy Scheme ambassador and the wife of inaugural Scheme Commissioner Sir William Hudson, the Lady Eileen Hudson TBM is excavating the 2.6km main access tunnel down to the underground power station cavern. The TBM is 137 metres long and has an 11m diameter – as high as a three-storey building.
