O-Bahn tunnel systems

SAGE delivered the essential tunnel systems required for the O-Bahn, including fire-life safety, ventilation, deluge pumping, and power monitoring systems designed to reduce whole-of-life costs.

The O-Bahn city access project involved the latest C-ITS innovations, incorporating bus collision avoidance, unauthorised vehicle detection, priority signalling and real-time travel data collection.


Cross Yarra Partnership

SAGE is the tunnel and building management control system designer and integrator for the Melbourne Metro Tunnel Project. 

SAGE’s responsibilities include the design and
delivery of automated control systems for this major railway project.

The Metro Tunnel Project is the largest public transport infrastructure project ever undertaken in Victoria, delivering twin 9km rail tunnels under Melbourne and five new underground stations. 


Predictive maintenance for tunnel jet fans

The twin Heysen Tunnels have adopted an innovative solution that leads the way in predictive maintenance.

The system detects wear and tear through sensors installed at 12 points on each fan that monitor the status of the fans and mounting brackets, via vibration trends.

SAGE Automation configured the SCADA and PLC components of the fan vibration monitoring system.


Smart tunnel maintenance and 24/7 support

Solutions such as predictive maintenance modernise the way maintenance is conducted on key assets and equipment used within tunnels, enabling greater diagnostics and predictability surrounding equipment maintenance scheduling and costs.

SAGE delivers seamless support to the transport sector at all stages of a project and beyond. The National Operations Centre provides a clear picture of your operational performance as well as remote real-time monitoring of assets, fault diagnosis and resolution.
