SYDNEY METRO, AUSTRALIA<br />
TECHNOLOGY<br />
THAT IS TOUGHER<br />
THAN ROCK<br />
As the largest public transport project in Australia, Sydney Metro will<br />
have a target capacity of 40,000 customers per hour when completed. Four<br />
Double Shield TBMs and one Mixshield TBM which tunnelled 40 meters<br />
below Sydney Harbour have built 31 kilometers of new tunnels. Equipped<br />
with project specific, powerful and resilient tools the Herrenknecht TBMs<br />
have been able to remove the highly abrasive Hawkesbury Sandstone.<br />
