The Port Melbourne railway line is a former railway line in Melbourne, Australia, opened in September 1854, that is now a light rail line. It was instigated by the Melbourne and Hobson's Bay Railway Company to carry passengers arriving in Victoria at Station Pier and to alleviate the high cost of shipping goods using small vessels up the Yarra River to Melbourne. The line's conversion to light rail occurred in 1987; it is now served by tram route 109.
