Problem to be addressed

The rail network servicing Sydney’s CBD is currently near capacity at peak periods, and some key routes are expected to reach capacity in the early 2020s. By 2036, demand is expected to exceed network capacity, causing material impacts on service accessibility, dwell times, and crowding in stations and trains. This will affect the overall reliability of the rail network, particularly where it provides access to the CBD.

The cost of these transport network constraints has been estimated at $2 billion in lost economic benefits per year over the next 30 years. A significant increase in transport capacity in key parts of the network, especially servicing the CBD and the corridor extending from the Airport through the CBD and north to Macquarie Park, will assist in realising employment growth and increased productivity.

Project description

Sydney Metro City & Southwest is the second stage of the broader Sydney Metro project. It will deliver 30.5 km of metro rail between Chatswood and Bankstown. The project has two stages: a 17.1 km section between Chatswood and Sydenham that is primarily tunnelled; and a 13.4 km section between Sydenham and Bankstown, involving conversion of the existing Bankstown rail line to metro operations.

The project includes new underground metro stations at Crows Nest, Victoria Cross, Barangaroo, Martin Place, Pitt Street, Central and Waterloo. The project will increase rail capacity through the Sydney CBD, improve capacity and reliability on the rest of the rail network, and enhance resilience of the wider transport network by delivering a second harbour rail crossing.

Economic, social and environmental value

The project’s major benefits will be for public transport users through travel-time savings and reliability improvements. New metro stations will improve accessibility to existing suburbs and precincts. The project will contribute to reducing rail and road congestion and enable housing and employment growth.

The proponent’s stated benefit-cost ratio for conventional benefits is 1.3, with a net present value of $2,775 million (7% real discount rate).
