Metro Proposal
Ron Christie's "Long-term strategic plan for rail" report suggested that several "metro" lines be built to service new areas and to relieve capacity on existing lines. These included a metro line to supplement the Illawarra Line. The route would go from Cronulla to Miranda along the existing tracks, then along a reserved corridor for the F6 Southern Freeway up to Sydney Airport. The line would then extend to the Sydney CBD then to Sydney's Northern Beaches via Chatswood. Christie suggested that even if the entire line were not to be built, the first stage between Cronulla, the Airport and the City would provide "essential capacity relief" for the Illawarra line which would be "severely capacity-constrained" within two decades. Both heavy rail and light rail were mooted as transport suggestions.
Christie was not the only person to suggest the F6 Corridor as an alternative. In 2002, former Minister for Transport Carl Scully officially abandoned the corridor, reserved since 1951 for the extension of the Southern Freeway north to St Peters, and suggested that light rail, bus-only roads or high-frequency train services could run on the corridor. He wished to encourage innovative public transport solutions in the area, while maintaining the green space available near Botany Bay. The plan received support from environmental groups, with environmental transport group EcoTransit proposing their own 25.5 km (15.8 mi) light rail line to supplement the Illawarra Line on the reservation, called the "Bay Light Express". Since 2005, however, the future of an alternative corridor has been in doubt, with State Treasurer Michael Costa announcing that the corridor would again be reserved for a motorway; however metro lines remain on the Government's agenda for the future and a rapid transit line supplementing the Illawarra Line may be possible in the future.
