The Upfield railway line is a suburban electric railway in the northern suburbs of Melbourne, Australia. The line has 15 stations and is located in PTV ticketing Zones 1 and 2. The future of the Upfield line was in serious doubt in the late 1980s and early 1990s with proposals for the line to be converted into a light rail line or even closure. However, the future of the line was secured in 1995 with the upgrading of the signalling, closure or upgrade of the numerous level crossings, and duplication of the track between Fawkner and Gowrie.
