CBD South station

CBD stations are currently experiencing intense crowding at peak times. The use of the five City Loop stations is projected to almost double from 580,000 passengers a day to 1.1 million in 2031.

Building Melbourne's new Metro Tunnel will free up space in the City Loop so we can run more trains in and out of the city.

Once operational, Metro Tunnel's CBD North and CBD South stations will more evenly distribute passenger flow and interchange movements in the inner core of the Melbourne rail network, with crowding across all City Loop stations expected to drop by about 20 per cent.

What you told us

Drawing on the ideas, expertise and opinions of stakeholders and the community is vital as planning for the Metro Tunnel continues.

A comprehensive program of public engagement and consultation has been underway for the Metro Tunnel since early 2015, and feedback has informed planning documentation and project designs.

Key CBD feedback topics included:

  • Potential for improved traffic, bicycle and pedestrian flows on busy city streets.
  • Requests to maintain access to car parks and residences during construction.
  • High interest in noise and vibration, construction working hours and mitigation measures for residents and businesses close to work sites.
  • The importance of maintaining access to shops and laneways, including delivery vehicle access, wherever possible.
  • Measures need to be taken to protect important buildings including Melbourne City Baths, St Paul's Cathedral and Flinders Street Station.

Station location and access

CBD South will be located directly under Swanston Street, between Flinders and Collins Street.

The station will include a direct underground connection to Flinders Street Station, allowing commuters to conveniently interchange between Metro Tunnel and City Loop services.

The station will improve access to Federation Square, Southbank, the Arts Centre, St Paul's Cathedral and Swanston Street shopping.

Entry points

It is proposed that CBD South station will have three main entrances:

  • The main southern entrance will be located at the southern end of Swanston Street near Flinders Street, and includes direct underground connection to Flinders Street Station.
  • A second southern entrance will provide a direct connection to Federation Square.
  • The northern entrance is to be located at the north-west end of City Square near Collins Street.

An additional entrance may also be delivered on Swanston Street, opposite City Square.

Access between street level to the platforms will be provided via escalators, lifts and stairs.

Ventilation shafts

CBD South station will include ventilation shafts to circulate air from the station concourses, platforms and tunnels for the comfort of passengers. They will also include exhaust systems that, in the event of an emergency, will quickly remove fumes from the station and tunnels. The Metro Tunnel will be used exclusively by electric trains.

The exact location of ventilation structures and station utilities will be finalised in consultation with local stakeholders as part of the project's planning and detailed design phases.

Direct access to the City Loop

The two Metro Tunnel stations in the CBD will have direct underground interchange with existing City Loop stations. Passengers will be able to interchange without touching off and on again from CBD South to Flinders Street Station and vice versa.

CBD South is designed so it can operate independently of the City Loop (e.g. with its own entrances, paid gates and ticketing office) to cater for expected patronage and ensure as much as possible that if one line experiences a disruption, it does not affect other lines on the network.
