Tram Power Upgrade - Thornbury substation

10 November 2017

Yarra Trams and Public Transport Victoria (PTV) wish to update you on the new tram power substation on Stott Street, opposite Kemp Street, in Thornbury.

Substation remediation

As you may be aware, PTV and Yarra Trams have built a new power substation on Stott Street, opposite Kemp St, in Thornbury. This location was been strategically chosen to provide power to nearby tram Route 11.

In late 2015, Yarra Trams received notification from its contractor, Siemens Zinfra, that the cement sheeting used in the flooring of their substation contained asbestos material. The material is isolated within the substation and access to this site has always been restricted to authorised personnel only.

The safety of the community and our employees is our priority and we have been working closely with WorkSafe to implement all necessary steps to ensure safety on site.

Based on expert advice received fromGreencap (a National Association of Testing Authorities (NATA) accredited organisation) we would like to assure you that the risk of exposure to the community is negligible.

In accordance with advice from WorkSafe, Siemens Zinfra carried out a 'clean and seal' within the substation on 17 Feburary 2016.

Siemens Zinfra is now preparing to remove the substation floor in order to remove the asbestos from the site.

This work will involve:

  • Cleaning of internal equipment
  • Preparations for removal of asbestos material
  • Removal and disposal of material containing asbestos
  • Sanitisation of the area
  • Post-sanitisation testing
  • Final clearance

This remediation work is internal to the substation and except for workers entering and exiting the site and the substation, will not be visible to the public.

Following this activity, testing and commissioning will take place inside the substation building.

This remediation work is expected to commence on 5 December 2017 and be completed by 21 March 2018. Work will be predominately carried out each weekday from 7am - 5.30pm.

During this time residents can expect to hear some construction-related noise. Our workers will be mindful of keeping noise to a minimum and respecting the needs of the local community.

Architectural treatment

We are pleased to advise that Aboriginal artist Yamba Ross has been engaged to complete the architectural treatment mural on the substation.

Yamba has successfully completed other similar large scale mural projects, including locally at the Preston Library and on a private residence on the corner of Christmas and Wales Street, Northcote. 

In addition to the substation mural, native landscaping within the substation site will occur, along with the removal of the current fence replaced with a low bollard-style perimeter fence.

Acoustic solution

In November 2015 a temporary mitigation solution was installed to minimise noise impacts from the substation air-conditioner units. This temporary mitigation has now been replaced with a permanent solution deemed necessary to reduce noise levels from the air conditioning units. The installation of this permanent solution has also allowed the mural treatment to proceed.

Providing a tram network for the future

Upgrading tram power is an important part of modernising Melbourne's tram network. This substation at Thornbury will provide power to nearby Route 11. Upgrades to substations will deliver a more reliable power supply to support high capacity trams as they are introduced across the network.

We thank you for your patience and understanding during this important upgrade work. For more information on this essential upgrade or if you wish to provide feedback, please call 1800 800 007 or email
