As part of Level Crossing Removal Authority (LXRA) program to eliminate Melbourne’s most dangerous and congestive level crossing. A 2x4MW Southern Cross substation was created nearby Southern Cross station to upgrade the traction power system identified through modeling as necessary to support the future deployment of the High Capacity Metro Trains (HCMT) on the Metro Trains Melbourne (MTM) network.


Developing a multi-story substation equipment layout design and optimization. Creating a 11 kV AC, 1500 V DC, low voltage AC and DC, communication and control cable reticulation design that supports 1500 V DC feeder interface design. Additionally, ensuring a negative return current system/track interface design.


Middleton Group played a key role in the design management, electrical & structural detailed design vendor interfacing and construction phase. It was necessary to develop architectural, structural, civil, mechanical, electrical, power, overhead wiring and earthing deliverables to a detailed design standard required to clearly articulate the project and design intent.


The team’s expansive knowledge in design management and electrical design allowed for all options for be evaluated and the most beneficial chosen to allow for an efficient project
