Metro Tunnel

Western tunnel entrance options

The western tunnel entrance for the Metro Tunnel is proposed to be located alongside the northern side of the existing rail corridor near South Kensington Station. A 'decline structure', or descending tracks, will be built so that trains can enter the new Metro Tunnel.

From the western tunnel entrance, the tunnels will pass under Moonee Ponds Creek and CityLink before connecting to the new underground station at Arden.

In late 2015 and early 2016, we sought community feedback through a range of mediums, including information sessions, meetings and our 'yoursay' online engagement portal. As a result of feedback received, and as part of our efforts to reduce potential impacts, we have developed two options for the location of the tunnel entrance, each with differing impacts.

The two options 'Option A' and 'Option B' - were assessed as part of the Metro Tunnel Environment Effects Statement (EES).

It is important to note the project designs are a concept only. The contractor appointed for construction will be responsible for developing the detailed project design (anticipated to be mid-late 2018) in line with planning approval requirements. This means that the eventual design solution may differ from what was presented as part of the Metro Tunnel EES. This is a common design process for major construction projects.

Western tunnel entrance option A

Western Tunnel Entrance Option A

In Option A, the tunnel entrance is proposed to be constructed in the rail corridor near the intersection of Childers Street and Ormond Street just to the west of the South Kensington subway.

This option requires a shorter decline structure and track work in the rail corridor between Kensington Road and the tunnel entrance.

Western tunnel entrance option B

Western Tunnel Entrance Option B 

In Option B, the tunnel entrance is located in the rail corridor further west along Childers Street approximately halfway between the station entrance and the Bill Vanina pavilion. The location of the tunnel entrance has moved slightly further east as a result of further design assessment undertaken since this Option was first presented to the community.

This option involves constructing a longer decline structure, track work either side of Kensington Road and the construction of a new rail bridge over Kensington Road.

Comparison between Option A and Option B

Impact Option A Option B
Property acquisition Permanent acquisition of nine residential and thirteen commercial properties Permanent acquisition of one residential property
Roads
  • Temporary closure of Childers Street, between Kensington Road and Tennyson Street during construction
  • Construction of a permanent retaining wall along Childers Street to the portal entrance
  • Temporary changes to traffic access and movements along Childers Street, Ormond Street, Altona Street and Tennyson Street and a temporary access ramp arrangement to McClure Road
  • Temporary closure of Childers Street, between Kensington Road and Ormond Street during construction
  • Construction of a permanent retaining wall along Childers Street to the portal entrance
  • Temporary changes to traffic access and movements along Childers Street and Tennyson Street
Parking

Rail corridor 

Extensive and more complex track and civil work in the rail corridor east of Kensington Road

  • Extensive track work both east and west of Kensington Road
  • Construction of new rail bridge over Kensington Road
Intake substation Option to locate an intake substation within the Lloyd Street Business Estate No intake substation located within the Lloyd Street Business Estate
Disruption
  • Noise and vibration impacts associated with a major construction site
  • More rail service disruptions required
  • Noise and vibration impacts associated with a major construction site
  • Less rail service disruptions
Cost Less expensive option More expensive option

The intake substation (ISS) will provide power supply to the new Metro Tunnel service. The ISS will house electrical equipment including transformers, where incoming power supply voltage will be stepped to a suitable voltage prior to feeding to the new twin tunnels and underground train stations. If western tunnel entrance Option A is selected, one of the locations being considered for the ISS is within the Lloyd Street Business Estate. If Option B is selected, the ISS will not be located within the vicinity of the western tunnel entrance.

It is important to note the project designs are a concept only. The contractor appointed for construction will be responsible for developing the detailed project design (anticipated to be mid-late 2018). This means that the eventual design solution may differ from what is presented as part of the Metro Tunnel EES. This is standard on all major construction projects.
