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.)

The only special signals relating to the grade crossings are small green
bulls-eye signals posted near the crossing.  They flash when the gates are
descending and glow steadily when the gates are down.  I have seen these on
other lines, such as the CSS&SB and ICG electric.

Speaking of rapid transit, is Chicago's the only one to use both third rail
and overhead wire for power?  I can't think of any.
