Tunnels South and Tunnels North Project Summaries

Suburban Rail Loop (SRL) will deliver a 90km rail line linking every major train service from the Frankston Line to the Werribee Line via Melbourne Airport, better connecting Victorians to jobs, retail, education, health services, and each other. SRL is more than a transport project - as Australia's largest housing project, it will help reshape how our city grows in the decades ahead.

SRL East will deliver twin 26km tunnels and 6 new underground stations at Cheltenham, Clayton, Monash, Glen Waverley, Burwood and Box Hill. It will also include a train stabling and maintenance facility to support the new rail line, an emergency support facility and power supply substations. SRL East has been under construction since 2022 and will be open in 2035.

The tunnelling works in respect of the Tunnels South and Tunnels North will be undertaken by separate contractors under separate Incentivised Target Cost (ITC) Delivery Deeds.
