The Upfield railway line is a commuter rail service operating between Flinders Street in the Melbourne central business district through Melbourne's northern suburbs including West Melbourne, North Melbourne, Parkville, Brunswick, Coburg, Coburg North, Hadfield, Glenroy and Coolaroo. 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.
