Rather a fascinating map.  It's interesting to see the proliferation of
lines in the area.  The map does not provide a key, however, so I assume
that the dark heavy lines are the Boston-Maine lines and all the others
represent various other railroad companies, rather like telephone
companies carving out their own little niches.
