The rail network of Melbourne, Australia, has a significant number of railway lines and yards serving freight traffic. Rail transport in Victoria is heavily focused on Melbourne, and, as a consequence, much of the state's rail freight passes through the metropolitan network. Although a limited number of electric freight services historically operated in the metropolitan area, a lack of electrical infrastructure on Victorian mainlines means that no freight services in Melbourne now use electric traction, despite some services operating over the electrified passenger network.
