The XPT was derived from British Rail's HST, with downrated engines, uprated suspension and a reduced top speed. As I recall, there was only 1 XPT crash at a level crossing, the notorious crossing on the Olympic Highway at Gerogery in NSW. In the run up to he XPT crash there had been numerous other crashes at the crossing, which ws eventually replaced with an overbridge called "Five Mates Crossing" after the five lads in the car who died as a result of the XPT collision.
