Planning is underway to upgrade the Eltham train substation and we are inviting you to have your say on some of the elements of what it will look like. The site upgrade will make it ready for bushfire protection technology, which is being installed on the electricity network.
The Victorian Bushfires Royal Commission 2009 made recommendations to reduce the risk of bushfires across the state. Damaged and failing electrical wires are a major cause of bushfire.
In response to the recommendations, power distribution companies are installing technology to the power network that will reduce the risk of triggering a bushfire. However, this technology may cause power surges to infrastructure, such as train substations that are connected to the network.
Train substations need to be ready for this technology to ensure power spikes do not impact your journey. An isolating transformer is being installed inside a Rapid Earth Fault Current Limiters (REFCL) building and it will work like a shock absorber and protect the train substation from high voltage spikes.
How are we upgrading the Eltham train substation?
Upgrading the existing substation at 1111 Main Road to make it ready forREFCL technology involves electrical work and the construction of a second building alongside the existing substation to house the REFCL technology.
- The new building will house an isolation transformer to protect the electrical train network.
- It will be smaller than the current substation and will be about 9 X 13 metres long and about 3 metres high.
- Works will include the construction of a retaining wall between the new building and the road and its adjacent footpath.
- The wall is required to structurally support the earth embankment alongside the building and to prevent access to the roof and surrounds of the new building.
- The wall will be up to 2.1 metres high adjacent to the footpath.
- Landscaping works will also be undertaken, with a mixture of plant types to maintain the character of the local area.
- Works around the building will include improving the driveway and access to enable future maintenance.
Works on site will commence from October 2021 and continue until mid-2022 (weather dependent) and be carried out in consultation with Nillumbik Shire Council as required.
Have your say on the retaining wall concept plan
The design of the retaining wall has been developed with consideration for:
- Safety and the protection of road users and pedestrians, and the substation infrastructure.
- Ease of construction, maintenance and sustainability.
- The design elements allow for an opportunity to respond to the neighbourhood character and the natural bushland features that are prominent in Eltham.
The dimensions of the substation and retaining wall will look like the image below. The new wall will sit atop concrete foundations that retain the road and earthworks below road level. Ironbark-coloured concrete panels will rise to 2100mm above the footpath with alternate panels clad in a rusted Corten steel with a laser cut pattern.
How to participate
We’re now asking the community for feedback on the external characteristics of the retaining wall. To participate, please complete the survey below.
The final concept with the chosen colour and steel pattern design will be shared with the community prior to works beginning in October 2021.
Critical infrastructure projects will continue during current COVID restrictions. This includes safety and maintenance works on roads and public transport, and road safety projects that maintain critical safe operations on the road network.
To ensure the safety of all workers and the community, all construction and maintenance work undertaken will operate under a COVIDSafe plan.
