There are a couple of Wheel Impact Load Detectors (WILD) up around Maitland
way, monitored, I think, from Maitland Box. These were introduced after an
NR train lost half a wheel early last year, but kept going for miles before
it derailed. The problem of course, once the impact is detected, is to
contact the train to stop it.
