Okay.  My favorite signals were/are on the Chicago and North Western
railroad.  They used semaphores (with moving parts, unlike the Pennsy
position signals you describe) with a red, yellow and green lens in
the moving portion.  The reason I wrote "were/are" in the above sentence
is that the North Western has replaced their semaphores on the line
going past my parents' house in Milwaukee with your standard "traffic
light" type color signal.  But I've continued to see semaphores around
Chicago.  I imagine it's only a matter of time before all of them are gone.
