A Wheel Impact Load Detector (WILD) is a small piece of trackside equipment
connected to a signalbox/control centre which measures the impact of wheels
on the rail. It was brought in after an NRC train on the north derailed
after leaving a trail of destruction from a broken wheel. Half the wheel was
missing. There are a few around, I think Emu Plains, Heathcote, Maitland
have them.
