South Improvement Alliance Passing Lanes No. 2 and No.14

Client: South Improvement Alliance
Duration of works: 2009 - 2010
Location: Victoria and New South Wales, Australia


  • Provided signalling design, data, project engineering, design management, principles and site testing, and commissioning for two passing lanes of approximately six kilometres.
  • The signalling utilised Microlok interlocking technology interfacing with existing Relay interlockings, and Microtrax for train detection and vital communications.
  • Level crossing protection was provided using Safetran GCP4000 and GE HXP grade predictors.

 The key challenges of the project were:

The project required complex technical interfaces to be implemented in a cost effective and robust way.

 The key milestones of the project were:

RCS Australia’s design, testing, management and scheme development resulted in high value and technically advanced engineering solutions that ensured successful and timely delivery.
