Sydney Metro’s second tunnel boring machine has broken through the rock at
Waterloo Station after six months of digging underground.

TMB Mum Shiri began at Marrickville on November 5 and has carved through
304,000 tonnes of rock — enough to fill 47 swimming pools — to build the
3.1 kilometre tunnel.

The TBM named after an Aboriginal woman who raised 60 foster children
installed 1815 reinforced concrete rings to form the tunnel from
Marrickville to Waterloo.

Transport Minister Andrew Constance said the breakthrough at Waterloo was a
significant milestone for the Metro project.

“While we’re about to open Sydney Metro in the northwest on 26 May, this
latest milestone shows the extension of metro rail into the city is moving
quickly as well,” he said.
