Melbourne Airport Rail is a once-in-a-generation transformation of Victoria's transport network, connecting Melbourne Airport with a rail service for the first time.

The Victorian Government has given the green light to progress the detailed Business Case for Melbourne Airport Rail, having selected the Sunshine Route as its preferred route.

Development of the detailed Business Case is now underway, with the project set to begin construction by 2022 subject to required approvals. Construction is expected to take up to nine years.
