the network via the South West Rail Link by 2015, and the rail line would pass through the new growth corridor from Ryde to the airport. Critics of the New South Wales government criticised what they perceived as a lack of follow through, citing the previously planned Parramatta to Chatswood rail link which had since been truncated to link only Epping to Chatswood, with the Epping to Parramatta portion postponed indefinitely. It would also have included quadrupled lines between St Leonards and Chatswood on the North Shore line. In 2006, Premier Morris Iemma placed planning controls along two potential corridors in the CBD (the MetroWest and MetroPitt routes) to secure future accessibility. Developers who wanted to excavate deeper than two metres within a 25-metre buffer zone of the corridors needed to seek RailCorp's approval. Parramatta Rail Link (PRL) In 2002, the State Government proposed a Parramatta-Epping-Chatswood link. That same year construction began on the latter half which was completed seven years later as the Epping to Chatswood railway line. However the other half was postponed indefinitely in 2003 by Transport Minister Michael Costa citing a lack of projected passenger numbers and economic viability. On 11 August 2010, the Rudd Federal Government promised $2.6 billion towards this project, which, along with the NSW State Labor Government, would have constructed a line from Parramatta to Epping through the Carlingford line. Work was due to start in 2011, with a prospected 2017 finish, but the O'Farrell government cancelled the project, instead requesting that Federal funding be diverted to a more expensive upgrade of the Pacific Highway. The Gillard Federal Government responded by revoking the funding altogether. North West Rail Link After its original announcement in 1998 for completion in 2010 as part of the Action for Transport 2010 plan, in 2006 the schedule was revised for completion in 2017 and later brought forward to a staged plan for train services to Castle Hill and Hills Centre in 2015, and to Rouse Hill by 2017. It was planned to be 22 kilometres in length, consisting of a 16 kilometre section in tunnel from Epping to the proposed Burns Road Station, followed by a 4 kilometre section above ground from Burns Road to Rouse Hill. Six new stations were proposed to be constructed at Franklin Road, Castle Hill, Hills Centre, Norwest, Burns Road and Rouse Hill. A train stabling facility was proposed at the north
