Artarmon substation

A planning modification went on exhibition in June 2017 proposing to relocate the Artarmon substation to 98-104 Reserve Road, Artarmon, within the Artarmon Industrial Area.

The Artarmon substation will supply traction power to the metro trains. The site will include an above-ground building for the substation and electrical equipment, and a shaft for the cables and maintenance access to the tunnels below.

Construction of the Artarmon substation will involve:

• Removing existing buildings
• Excavating a vertical shaft to the tunnels below. This is likely to be carried out using a large diameter piling rig or raise bore. Drill and blast or penetrating cone fracture techniques may also be used
• Lining and reinforcing the shaft
• Building above-ground components
• Installing electrical equipment
