We've got a crossing near where I live that's a bad one. The rails cross at a diagonal at Ill.64 and Addison Road in this town, and the sight lines are terrible.
One day a few years back a truck thought he would beat the train, so he crossed. Unfortunately the light had changed and traffic in front of him had stopped for the light. So, Einstein began leaning into his airhorn to get the traffic to move so he could clear the track, but--- well, I guess you don't have to be told. The train hit the rear of his trailer, pushing him into the car ahead of him. I think there were injuries but no deaths at this accident, and the car the truck was pushed into was totaled, and the truck-driver went to jail on several charges. It didn't help his case that a train-buff on a nearby hill had taped the whole incident and gave the tape (yes, this happened that far back) to police.
Since those days, another incident at another crossing-- this one involving a school bus-- has caused authorities to re-think certain things, like making sure you get an idea if your vehicle will clear. They have markings on the road now, and if your vehicle won't clear those markings you can't legally cross the tracks if the traffic-control signal at the nearby intersection is red. The markings give you a buffer zone between you and the nearest rail on each side of the tracks just so you know where it's safe.
