Rail signal power and DC track electrical work involves installation, testing, fault-finding and maintenance of signalling power supplies, location cases, point machines, track circuits and DC traction-adjacent equipment within the rail corridor. The work is classified as High Risk Construction Work under WHS Regulation 2011 r291 because it involves energised electrical installations, work on or near roads or railways used by traffic, and frequently occurs under live possession or adjacent line open (ALO) conditions. A SWMS is mandatory before work commences and must be developed in consultation with workers, signed on by every person entering the work area, and kept available for inspection until the work is complete (and retained for at least two years if a notifiable incident occurs). This template addresses DC traction return path hazards, signalling power isolation, track interface risk and possession protocol integration so signal electricians, testers-in-charge and protection officers can demonstrate compliance across all eight Australian jurisdictions.
Hazards identified
7 hazards covered, sorted by priority.
Cardiac arrest, deep thermal burns, fatality from sustained DC current with no zero-crossing to break arc
Fatal blunt force trauma; PCBU and protection officer face industrial manslaughter exposure
Second and third degree burns to face and hands, retinal damage, hearing loss from blast pressure
Electrocution of worker downstream; signalling system corruption causing wrong-side failure and collision risk
Ventricular fibrillation from rail-to-earth potential difference exceeding 50V touch limit
Acute lumbar disc injury, crush injuries to hands, chronic musculoskeletal disorder
Chemical burns to eyes and skin, respiratory irritation from hydrogen off-gassing in unventilated huts
Control measures
Hierarchy-of-controls order: elimination → substitution → isolation → engineering → administrative → PPE.
- 1Elimination — Schedule signalling power and DC track work inside a track-closed absolute possession with traction power discontinued and earthed, removing both rail traffic and live conductor exposure entirely.
- 2Elimination — De-energise and prove dead the complete signalling feeder using a two-pole tester proven on a known live source before and after the test, per AS/NZS 4836.
- 3Substitution — Replace live fault-finding with offline data logger downloads and remote condition monitoring where signalling architecture permits, reducing time spent inside energised cubicles.
- 4Substitution — Use sealed valve-regulated lead acid (VRLA) battery banks in place of vented flooded cells to remove acid splash and hydrogen accumulation hazards.
- 5Engineering — Install permanent fixed earths and short-circuit straps on traction return rails within the worksite limits, verified by the protection officer before access is granted.
- 6Engineering — Apply lockout-tagout to signalling power isolators using personal danger tags and key-retention boxes compliant with AS/NZS 4836 clause 8 isolation hierarchy.
- 7Administrative — Conduct a documented pre-start SWMS sign-on with the tester-in-charge confirming possession limits, isolation boundary, emergency egress and adjacent line status before tools are deployed.
- 8Administrative — Maintain continuous radio communication with the network control officer and protection officer; cease work and clear to the designated position of safety on any train movement warning.
- 9PPE — Wear arc-rated coveralls (minimum ATPV 8 cal/cm²), Class 0 insulating gloves with leather overgloves, AS/NZS 1337 face shield and AS/NZS 1801 hard hat when working on energised signalling equipment.
- 10PPE — Wear AS/NZS 4602.1 day/night high-visibility rail-spec garments, AS/NZS 2210.3 safety footwear and acid-resistant gloves and goggles when handling battery electrolyte.
Applicable Codes of Practice
Mandates SWMS preparation, worker consultation, sign-on and retention for energised electrical work and work near rail traffic before commencement.
Prescribes isolation, testing for dead, earthing and access permit procedures applied to signalling power supplies and location cases.
Establishes PCBU duty to assess arc flash, induced voltage and DC hazards and to implement the hierarchy of control for live electrical work.
Defines protection officer competency, possession authority, lookout-driven worksite and absolute possession arrangements governing access to the rail corridor.
High-Risk Construction Work triggered
Signalling power feeders, location case bus bars and DC traction return bonding remain energised or carry induced voltage during fault-finding and changeover work.
Track circuit, point machine and lineside cable work occurs within the danger zone of operational rail traffic during adjacent line open possessions.
Possession worksites involve road-rail vehicles, tampers and rail-mounted plant operating in close proximity to signal electricians on the formation.
The PCBU must prepare, consult workers on and retain the SWMS; failure attracts substantial and indexed penalties — the current maximum follows the prevailing WHS schedule and rail safety law.

Worked example
On a suburban resignalling project upgrading a regional junction, a signal electrician arrives at the 0200 possession to replace a failed location case power supply on the down main. The tester-in-charge opens the SWMS at the pre-start brief, walking the four-person crew through hazard line 1 (DC traction contact) and hazard line 4 (inadvertent re-energisation), then confirms with the protection officer that absolute possession has been granted, traction is discontinued, and fixed earths are applied at both worksite limits. Each worker signs on against the controls, specifically acknowledging the lockout-tagout point on the feeder at the signal hut and the position of safety beside the cess. During work, the electrician identifies an undocumented parallel feed from an adjacent location — a deviation from the SWMS scope. Work stops. The tester-in-charge reconvenes the crew, marks up the SWMS with the additional isolation point, re-tests for dead using a two-pole tester proven live-dead-live on a known source, and obtains fresh sign-on before resuming. The amended SWMS is photographed and uploaded to the project compliance register. At handback, the protection officer confirms earths are removed, the document is filed for the two-year retention period, and a lessons-learned note is forwarded to the signalling design team for permanent feeder labelling at that location.
