Key benefits

The North Strathfield Rail Underpass Project:

  • enables additional paths (opportunities for freight travel) and reduce waiting times for freight trains
  • increases reliability of both freight trains and passenger services
  • removes the need for freight trains to cross lines at North Strathfield Junction which impacts passenger train services
  • enables a 1,500 metre freight train to stand clear of the Main North Line so other trains can pass before entering the single track section towards Flemington.

Project status

The North Strathfield Rail Underpass Project was approved in October 2012.  Major work was completed in June 2015.

The North Strathfield Rail Underpass Project was commissioned during the June long weekend and freight services have started using the new infrastructure.
