As part of the Sunbury Line Upgrade, we are delivering power upgrades that will allow bigger, more modern trains to run on the Sunbury Line. A new electrical substation is being built in Delahey on a closed section of Sydenham Road, in an open space reserve next to the rail corridor.

The building design will use neutral colours and materials, blending into the surrounding grasslands and clay soils.

A fence will be built around the perimeter of the compound to secure the substation and access driveways connecting to Sydenham Road will be built. Native grasses will be planted at the site, integrating the substation into the surrounding environment.

Construction impacts

Works will be carefully planned to limit disruption to commuters and the local community. However, activities may create noise, dust and vibration typical of construction activities.

A site compound has been established in the area to support the substation works. The compound accommodates site facilities, equipment laydown and create a safe barrier between the construction site and pedestrians.

Detours and signs will be in place during construction to ensure the safety of the community and workers.

There may be some unavoidable disruption to rail services so the work can be undertaken safely. Bus replacement services will be provided during any planned disruptions.

At times, out of hours works will also be required. Advance notification will be provided.

Construction timeframes

Works at the Sydenham Road substation project site and within the rail corridor are underway.

Site establishment activities began in mid-2021 with major construction of the substation now underway. The substation will be completed by early 2022.
