Project benefits

The Sunbury Line Upgrade is due to begin construction in late 2019 and is scheduled for completion by the end of 2023.

Why is the Sunbury Line Upgrade needed?

Patronage on the Sunbury Line is increasing at a rapid rate with demand set to exceed capacity in the next decade.

The Sunbury Line Upgrade, in conjunction with the Metro Tunnel, will deliver major improvements in capacity, reliability and frequency of services on the Sunbury Line.

Rail Projects Victoria is delivering this upgrade as we build the Metro Tunnel.

Community and stakeholder engagement is an important part of the planning and delivery of the Sunbury Line Upgrade. There will be opportunities to provide input as the project progresses.

What are the benefits?
