Leighton-Downer Joint Venture has received the contract to complete the final work on the Victorian Regional Rail Link.

According to the Victorian Government, the $43 million contract will be to design and construct the West Werribee Junction work package.

Leighton-Downer Joint Venture’s award package is the last of six contracts involved with the project.

Previous contracts have included John Holland, Abigroup, Coleman Rail, AECOM & GHD.

Approximately 5600 people will be employed either directly or indirectly on the project, according to the Victorian Government.

Victoria's three largest regional cities, Geelong, Bendigo and Ballarat, will soon have their own dedicated tracks through the metropolitan system, the Victorian Government said.

This will improve the capacity and on-time performance for metro and regional services.

According to the federal Department of Infrastructure and Transport, the Australian Government committed $3.2 billion to the Regional Rail Link through the Nation Building Program.

Capacity will be increased for all commuters by separating the regional and metropolitan lines, with modern station building and pedestrian bridges providing vital connections between the shopping, school and residential precincts.

It is set to “move more people, to more places, more often” by early 2016, upon completion for be enough capacity for extra train services to move up to 9000 extra passengers across the network during peak times.

“This significant investment in Australia's transport networks will ensure everyone can have access to services, education and jobs,” the Victorian Government said.
