Oh, that was on purpose?  Oops.  JOSM validator complains about them, so
I've been merging them where I find them.

To me, it makes sense to combine them.  If a car will have to drive over
the tracks, then they should share the same node, it seems.

I haven't really thought it through.  How does it help to have them be
separate nodes?
