[OSM-talk] level_crossing, leveled

[John F. Eldredge]

True, but it might well derail a locomotive in the winter.  I once saw a  
locomotive derailed by mud that had flowed across the track, then frozen..   
Fortunately, the locomotive was moving slowly enough that it didn't cause a  
catastrophic accident.

30cm of asphalt on a warm sunny day is no barrier to a 170 ton
locomotive. Think of a marshmellow being run over by a car.
