	Chicago's rapid transit lines (CTA) have several stretches that
	have road crossings at grade.  They are on the Evanston,
	Skokie, Ravenswood, and Douglas lines.  (What is now the Skokie
	line was originally built for the Chicago North Shore &
	Milwaukee interurban.)

Are these lines third rail or overhead?  I would think that the dead spot in
the third rail and easy public access to the third rail would rule out grade
crossings, unless all the cars were electrically connected for power,
something that Boston seems not to do (each car will individually darken as
the train passes a gap).

However, on the former NYNH&H Shore Line (now Amtrak), there are
drawbridges that don't have overhead; all the lights go out and the train
coasts over them.
