Corinda and Caboolture Substation Upgrades
Degnan delivers critical site integration works for Queensland’s rail network
Degnan delivered critical integration works for the Corinda and Caboolture substation upgrades, strengthening power reliability across Queensland’s rail network. These projects showcase our expertise in energy infrastructure, operational planning, and complex stakeholder coordination in live environments.
Through careful integration of high-voltage systems, advanced switchgear, and modern transformer technology, we provide resilient, future-ready power solutions that support major rail initiatives, including Cross River Rail. Degnan combines technical excellence, precise program management, and safety-focused delivery to ensure operational continuity, minimise disruption, and maximise long-term network performance.
Caboolture Substation
Degnan managed site integration construction, including coordination with switchgear and transformer contractors. Key works included:
New switch room with Gas Insulated Switchgear
Two high-voltage Centre-Tapped Transformers with containment bunds and firewalls
Overhead line masts, oil/water separation systems, extensive conduit and cabling
Civil upgrades to the facility
Corinda Feeder Station
Degnan completed major works to support the Queensland Rail network, including:
New switch room and auxiliary supply transformer
LV distribution board and high-voltage isolators
Overhead line masts and upgraded conduit syste
These upgrades future-proof the network by providing backup power for Cross River Rail and other major initiatives.
Community Connection
Beyond its technical advancements, the Queensland Rail also adorned the building with vibrant murals by local artists The Brightsiders, celebrating the region’s unique flora and fauna as part of the rail operator’s Positive pARTnerships program.
We’re proud to continue our partnership with Queensland Rail to deliver critical, beautiful, and enduring infrastructure for local communities.
Overcoming Challenges Delivering upgrades in live operational environments required careful planning and precision:
Earth grid management: Temporary configurations were modelled to maintain safety during trenching and civil works.
Stakeholder coordination: Close collaboration with Queensland Rail, switchgear suppliers and Energex ensured smooth shutdowns and safe cutovers.
Program efficiency: Critical works were sequenced within tight windows to maintain operational safety and minimise disruption.
History
- The existing Corinda Feeder Station is the oldest in the network, being constructed in the late 1970s.
- Caboolture Feeder Station is the third oldest and has been in operation since 1982.
