Originally, the railroads were concerned with the streetcars overhead, such as if the pole became disconnected, stalling the car momentarily. Ohio Brass and others went to great lengths to get around this problem, usually by means of running an energized metal cage shaped like a half-circle around the overhead, so if the pole became disengaged, it would continue to be energized in the cage. Historically, railroads have been against all crossings, and in some instances, gang fights have broken out between rival electric and steam railway workers where a crossing was being put in place.

That reminds me--the last time I rode the line I couldn't see any protective cage on the wire at the crossing and wondered whether its absence represents an unnecessary safety risk. It takes a while for the operator to walk back and replace the pole on the wire.
