The [[Network Development Plan – Metropolitan Rail|2012 Network Development Plan]] identified the need for a north–south tunnel connecting the Cranbourne and Pakenham lines to the [[Sunbury railway line|Sunbury line]].<ref name=":22">{{Cite web |title=Growing Our Rail Network 2018–2025 |url=https://www.ptv.vic.gov.au/footer/legal-and-policies/growing-our-rail-network-2018-2025/ |access-date=11 December 2022 |website=Public Transport Victoria}}</ref> In 2017, the [[Metro Tunnel]] began construction, involving the construction of five new underground stations, twin {{convert|9|km|adj=on}} tunnels, and other associated infrastructure improvements. Leaving the existing Cranbourne line alignment before [[South Yarra railway station|South Yarra station]], new stations will be built at [[Anzac railway station|Anzac]], [[Town Hall railway station, Melbourne|Town Hall]] (with connections to [[Flinders Street railway station|Flinders Street station]]), [[State Library railway station|State Library]] (with connections to [[Melbourne Central railway station|Melbourne Central]]), [[Parkville railway station|Parkville]], and [[Arden railway station, Melbourne|Arden]], before continuing onto the Sunbury line. These works will be completed by 2025, and upon completion, will create a singular rail line from Cranbourne and Pakenham to Sunbury and [[Melbourne Airport]] ([[Melbourne Airport rail link|from 2029]]).<ref name=":43">{{Cite web |last=Victoria's Big Build |date=28 November 2022 |title=About the Metro Tunnel Project |url=https://bigbuild.vic.gov.au/projects/metro-tunnel/about |access-date=9 December 2022 |website=Victoria’s Big Build}}</ref>
