Construction in Kensington
The western tunnel entrance will enable the Sunbury line to peel off from the existing rail corridor near South Kensington Station, and travel via the Metro Tunnel to join up with the Pakenham / Cranbourne line.

Overview of current works
The works occurring this year include site establishment and the removal and relocation of existing high voltage (HV) transmission towers.
How we will build the tunnel entrance
Once the Metro Tunnel is operational by 2026, the western tunnel entrance will allow for a new cross-city line to run between Werribee and Sandringham, servicing South Kensington station. This will allow for an increase in the number of trains that service South Kensington station; a benefit for all local residents travelling by train.
Frequently asked questions
Where will the western tunnel entrance be located?
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.
The final technical solution for the western tunnel entrance will be determined through detailed design by the appointed Rail Infrastructure Alliance contractor, anticipated to be mid-late 2018.
How will the western tunnel entrance be built?
The western tunnel entrance will involve construction works on Childers Street to build a retaining wall to support the embankment on the northern side of the rail corridor, which is to be widened to accommodate the new Metro Tunnel tracks.
A 'decline structure,' or descending tracks, will be built so trains can enter the new Metro Tunnel. The decline structure and tunnel entrance are proposed to be built via a 'cut and cover' method, which will see them excavated from the top down and the surface then reinstated over the top of the tunnels. A tunnel boring machine (TBM) retrieval box will also be built on Childers Street to support tunnelling works. To enable construction activities, a support site on Hobsons Road is also proposed.
How will the project affect traffic and parking in the area?
During construction, Childers Street will be closed to traffic and used for construction activities. This will require the occupation of car parks along Childers Street and the permanent diversion of the shared use path along the railway line. We are looking at options to offset this loss of parking.
In addition to the temporary closure of Childers Street, the construction of the western tunnel entrance may impact traffic and car parking on Ormond, Tennyson and Altona streets and within the Lloyd Street Business Estate during different stages of works.
We are aware of the need for oversize vehicles to access the Lloyd Street Business Estate via Childers Street. The project will endeavour to maintain this access when possible. There may be instances where maintaining access along Childers Street will not be possible. During this time, contractors will be required to engage with businesses and provide advance notification.
Throughout construction, contractors will be required to develop and implement measures to minimise disruption to traffic and parking in the local area by complying with Environmental Performance Requirements developed through the Environment Effects Statement process.
Will there be any upgrades to South Kensington Station?
Upgrades to South Kensington Station are not currently within the scope of the Metro Tunnel.
The Metro Tunnel will connect the Sunbury and Cranbourne / Pakenham lines for the first time, creating a new end-to-end line through the city. While the new twin tunnels won't connect to South Kensington Station, the Werribee line, which currently services South Kensington Station, will benefit from the additional capacity and reliability created by the project.
When the Metro Tunnel starts operating by 2026, a new cross-city line will be running between Werribee and Sandringham. This will allow more train services to operate through South Kensington Station, a benefit for all local residents travelling by train.
What impact will the project have on JJ Holland Park?
The Metro Tunnel is currently in the planning and development phase and any impact to surrounding parklands is being determined as part of the detailed planning process. Recognising that JJ Holland Park is highly valued by the community and the adjoining residential neighbourhood, the project team has worked to avoid having any impact on the park itself.
JJ Holland Park will remain open throughout the Metro Tunnel build.
