I am only speculating, but I think in Europe at least, there is a tendency to avoid railway crossings with rails that run parallel to another road. And if that cannot be avoided, the trains are required to run very slowly along those tracks. Part of the problem here is that the trains are unable to stop in time, because these are high speed tracks.
