part of a future high-speed rail line to Geelong. Avalon Airport management acknowledge that current patronage cannot justify a rail branch to the airport. Their preference now is for an "Avalon Airport" station to be provided on the existing Melbourne to Geelong rail line. It would also function as the terminal for the airport, from which passengers would be transported, using an unspecified type of people mover, on a four-minute, four-kilometre journey to the departure lounge, using the corridor set aside for the airport rail branch. Northern suburbs Albion–Jacana line In 2008, the Greens proposed standalone electrification of the Albion-Jacana railway line, with new passenger stations at Sunshine North, Keilor East, Westfield Shoppingtown, Airport West and Gowanbrae. Craigieburn line The 2013 PTV NDPMR proposed electrification of the Craigieburn line as far as Wallan. Upfield line The construction of a branch line was proposed between Flemington Bridge Station and Pascoe Vale Station in the early 1890s as a means of reducing Melbourne's rising unemployment rate. Three stations were planned, tentatively named Bent Town, Munroville and La Rose. A spur line branching from the Upfield line along the former Inner Circle rail easement to Princes Park, was proposed by the Public Transport Users Association in 1991, primarily as a means of transporting sports fans to the football ground. The PTV NDPMR proposed re-activating the former connection between Upfield and the Craigieburn line at Somerton. Such a project, in conjunction with duplication of the Upfield line, would enable diversion of Seymour and Shepparton services away from the at-capacity Craigieburn line, and provide additional capacity for electrification to Wallan. A business case is expected to be complete in 2019. North-eastern suburbs Doncaster line A variety of proposals for railway lines to the suburb of Doncaster have been made since the mid-20th century, although none have commenced construction. The City of Manningham is the only metropolitan Melbourne council area not served by a heavy rail line, and most proposals have envisaged a junction with the Hurstbridge and Mernda lines near Clifton Hill. Public transport advocates have claimed that the most frequently proposed route, along the median of the Eastern Freeway, will be jeopardised by construction of the North East Link, permanently precluding construction of the rail line. However, construction authorities have stated that the reservation will continue to be suitable. Hurstbridge line An extension of the Hurstbridge line to East Reservoir, was proposed in the
