a line between Merrylands and Green Valley, a line to the Northern Beaches, including a new underground section through Crows Nest, the complete Eastern suburbs line to Kingsford, already under construction at the time but later truncated to Bondi Junction (opened 1979), an extension of the East Hills line from East Hills to Glenfield (later constructed and opened in 1987), an express line between Redfern and Parramatta, running parallel but north of the existing Main Suburban line, a line connecting the Bankstown line at Sydenham with Redfern via Mascot and Alexandria, with a possible future branch to Sydney Airport, an extension of the Carlingford line to meet the Main North line at Beecroft, with an intermediate station, a connection between the Carlingford line at Rosehill and Parramatta The rail plans also involved significant duplication and quadruplication of existing lines. Despite extensive modelling, the vast majority of the proposals outlined were not constructed. Eastern Suburbs Railway, 1960–70s In 1967, the NSW government recommenced construction on the dormant Eastern Suburbs line that had been partly constructed and had lain dormant since 1952. The original proposal was for a line to Kingsford via Bondi Junction, Randwick and the University of New South Wales. In 1976, the project was curtailed to Bondi Junction, and the full line to Kingsford was not constructed. MetroWest proposal, 1990 In 1990, the State Rail Authority undertook a feasibility study into the development of a new underground line along the western edge of the central business district. Called MetroWest, the proposal called for the construction of a new underground line between Redfern and Wynyard along the western edge of the CBD with a new underground station complex at Central station, new stations in the Haymarket and Market Street areas, and terminating at a remodelled Wynyard station. The proposal would include platforms suitable to fit longer InterUrban passenger trains from the Central and South Coasts and the Blue Mountains, running through the new line in lieu of terminating at Central. The line underwent a two-year feasibility study and the corridor remains protected for possible future development with planning buffers placed along the corridor in 2006, however plans presently remain unrealised. It was later realised that around $400 million was wasted after this proposal was cancelled. Action for Transport 2010, 1998 In 1998, the NSW government released a position paper on various road and public transport projects to be delivered before
