The Metro Tunnel, PPP Tunnels and Stations

Project Overview

The Metro Tunnel, PPP Tunnels and Stations project is one of Victoria’s most significant public transport investments, delivering twin nine-kilometre rail tunnels beneath central Melbourne and five new underground stations at Arden, Parkville, State Library, Town Hall and Anzac. As bid leader, financial advisor, debt and equity arranger, equity investor and long-term asset manager, Capella Capital is playing a central role in structuring and delivering this complex city-shaping PPP through the Cross Yarra Partnership consortium.

As the largest transformation of Melbourne’s rail network since the City Loop, the project has expanded capacity, improved connectivity and unlocked faster, more reliable journeys across the metropolitan network. By linking the Sunbury, Cranbourne and Pakenham lines through the new tunnel, it relieves pressure on the City Loop and creates room for more frequent services across the broader network.

Project Benefits

  • The Tunnels and Stations package will create more than 5,000 jobs, including apprentices, trainees and engineering cadets.
  • Nearly 4,000 direct jobs created within the community
  • Automatic train supervision between Sunbury and Pakenham East
  • New train/tram interchange at Domain
  • High capacity signalling from Watergardens to Dandenong
