if you are on an expressway, and often roads smaller, usually grade crossings are avoided if possible. either the rail is on a bridge, and the road dips under, or the road is on a bridge and crosses the rail. it won't show as a hazard on the route in either of those cases.
You are still not wrong about our rail system, god forbid a passenger train hold up a freight train for one second, won't someone think of the shareholders???
