If that incident was investigated according to the current aviation-led model of the ATSB conducting very narrow scope investigations purely aimed at assigning fault, that recommendation wouldn't have been made then and it would have waited until there was an incident where the non-use of the headlight was directly involved, maybe one where the train got derailed and passengers killed. The decision to use headlights at all times would inevitably have come at some later point, but only at the expense of lives lost in a later incident which were thankfully saved by that decision coming earlier.Really? Was not the ATSB method of investigation, that of finding the cause, but not necessarily fault, the bone of contention in the Whyalla Airlines crash some years ago?
The SA Coroner who was looking for someone to blame, perhaps more accurately to take the liability, for the crash was very critical of the ATSB's no-fault approach and came to a much different conclusion based not on the facts of the crash but on legal argument about possible causes.
The use of daytime headlights was already practice in other railway systems.
