Description Of Project<\/h2>\n\n\n\n

The $8.3 billion North West Rail Link (NWRL) created a vital rail connection between Rouse Hill and the greater Sydney Rail Network, and was the first step in the NSW government\u2019s city changing plan to provide fast, safe, efficient, single deck train services into the heart of Sydney via the Sydney\u2019s Rail Future concept. The project consisted of twin 15km tunnels from Bella Vista to Epping \u2013 Australia\u2019s longest rail tunnels, as well as the delivery of eight new stations.<\/p>\n\n\n\n
