The Murray Basin Rail Project is a major railway project in the north-west of Victoria, Australia. The project includes the conversion of a substantial portion of the Victorian freight rail network from the historical broad gauge to the standard gauge used in other parts of Australia, and the upgrading of track to enable higher axle loads for more efficient intrastate freight transfer.
The project is part of the Regional Rail Revival program and is being delivered by V/Line in its role as infrastructure manager of the Victorian rail network, under the direction of Public Transport Victoria. The project is jointly funded by the Victorian and Australian governments. Construction commenced in 2016 and was supposed to be completed by late 2018. However, the project stalled in 2018–2019, with half of the project still uncompleted. The project resumed in 2021, with majority of works completed by late 2023.
