Engineering Controls, TAIC Findings, and Exposure in Rail Work Environments

Abstract

The rail corridor remains one of the most unforgiving operational environments in New Zealand, where the margin for error is effectively zero. International experience has shown that SPAD (Signal Passed At Danger) events can result in catastrophic outcomes, while locally New Zealand has experienced multiple near misses during periods of major rail activity, including during the Auckland electrification programme and more recently with passenger services.
