The first track has been laid as part of Stage 1 of the $230 million Richmond Line Duplication project.
The rail duplication, the new carpark at Quakers Hill and the Quakers Hill Station redevelopment are part of the project.
Construction is due to be completed in late 2011.
Construction on the new station at Schofields began earlier this year. The new Schofields Station will include a commuter car park, lifts, a bus interchange, taxi zones and kiss-and-ride facilities.
