Frankston line between Moorabbin and Highett stations to beachside suburb Beaumaris A new Mornington railway line from Frankston to Mornington via Mount Eliza The report recommended against a line to Doncaster due to the high cost of tunnelling. 1969 Melbourne Transportation Plan A major plan released by the Victorian state government of Henry Bolte called for the creation of 510 kilometres of freeways, and a number of new rail lines. The plan proposed: An underground rail loop in central Melbourne A line to Doncaster connecting with the network at Victoria Park station A line to Monash University Clayton An extension from Altona to Westona An extension from Huntingdale to Ferntree Gully A new line connecting Dandenong and Frankston Several extensions of suburban electric service along existing lines to Werribee, Rockbank, Sunbury, Craigieburn, Coldstream, Hastings and Mornington None of these proposed lines were ever built, except for the underground rail loop which began construction in 1971 and progressively opened between 1981 and 1985. The lines to Werribee, Sunbury and Craigieburn were also eventually electrified. 1999 Linking Victoria A strategy launched in 1999 by the state government of Steve Bracks called for an airport rail link to Melbourne Airport and the reopening of several regional railway lines. 2008 Victorian Transport Plan The government of John Brumby responded to a major increase in rail patronage by releasing a plan in 2008 that called for a number of rail extensions, including the Regional Rail Link from West Werribee to Southern Cross station, a new inner-city rail tunnel called the Melbourne Metro Rail Project, and electrification of the rail network to South Morang (completed in 2011), Sunbury (completed in 2012), Melton and Cranbourne East. 2013 Network Development Plan: Metropolitan Rail (NDPMR) New government agency Public Transport Victoria (PTV) released a detailed 20-year rail development plan in 2013 under the government of Denis Napthine. The report outlined a major expansion of the metropolitan rail network in Melbourne over a number of stages, with the goals of introducing a 'metro-style system' and extending the reach of the network. Significant projects identified for construction included the Metro Tunnel, the Airport rail link, a line to Doncaster, a line to Rowville, a second underground inner-city rail tunnel, and many rail electrification and duplication projects. Extensions under construction Metro Tunnel There have been numerous proposals for a north–south tunnel in inner-city Melbourne, to relieve capacity on Melbourne's City Loop and
