North Strathfield Rail Underpass

The Northern Sydney Freight Corridor (NSFC) Program is part of the Commonwealth Government’s Nation Building Program. Feasibility studies undertaken for the NSFC program have recommended a staged series of projects along the Main North corridor. Stage 1 of this program of works is scheduled for completion in 2015. The NSFC Stage 1 (NSFC 1) program includes 4 projects including:

  • Hexam Passing Loop
  • Gosford Passing Loops
  • North Strathfield Rail Underpass
  • Epping to Thornleigh Third Track

The North Strathfield Rail Underpass project will enable the Up-Freight traffic movements on the Main North line to access the Strathfield Goods Loop by passing under the Main lines via a new dive and tunnel structure, instead of through the current flat junction. This in turn relives on of the most serious bottlenecks for the Freight and Passenger Services on the Main North Line. In addition to the new dive and tunnel structure there will be 3.2km on new track and a complete rebuild on Concord West Station precinct.
