Sydney Trains - Electrical Isolation Improvement Program (EIIP)

The scope of the EIIP includes upgrading infrastructure assets over a five-year period to enable Remote Isolation Rail Connecting Systems (RIRC) to operate within the Sydney CBD, including all substations, sectioning huts, and trackside field switches that use in-maintenance configurations.
The EIIP will improve the safety, speed, and efficiency of the 1500Vdc and High Voltage (HV) Electrical Power Outage System (EPOS) through the introduction of improved systems, processes, and technology.

Scope :

For the EIIP, the CWG team were vital in providing safety assurance support to the project within a strict timeline for Gates 2-5. Our key works included:

  • Providing subject-matter-expertise in general systems engineering as well as specialist knowledge in system safety assurance
  • Working closely with stakeholders in developing the safety assurance artefacts (PHA, SHA/IHA, Haz Log, SAR, etc.)
  • Developing evidence-based safety assurance arguments (SAS/SAR) for CCB Gates 2-5.
  • Planning and Organising WHS specific consultations with relevant stakeholders for each EIIP release.
