Works around Delahey

As part of the Sunbury Line Upgrade, a range of enhancements will be delivered to allow bigger, more modern trains to run more frequently on the line once the Metro Tunnel is complete. A review of the existing train power supply and future transport needs along the Sunbury Line show that power upgrades are needed in this area.

Construction of a new electrical substation is part of essential rail power upgrades happening in Delahey. The new substation will be built on a closed section of Sydenham Road, in an open space reserve next to the rail corridor.

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 construction site will be established in the area to support the substation works. It will accommodate site facilities, equipment laydown and create a safe barrier between the construction site and pedestrians.

To facilitate works in the area, 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 to local residents ahead of all out of hours construction activities.
