Central Walk is a new 62ft (19m) wide underground pedestrian concourse at Central Station that will connect passengers to trains, light rail, and new Sydney Metro underground platforms. A Grydale JMS-50-MES was the best solution to provide ventilation and dust control during this project.

The Melbourne Metro Stations will be built as trinocular caverns, where three overlapping tunnels will be mined by roadheaders to create one of the widest metro platforms in the world...
