RAILROAD SIGNALS of the U.S.
TRI-LIGHT SIGNALS
This page covers signals nicknamed "tri-lights", otherwise known as color light signals. I've had several people call me to task on using "tri-lights" for this style, telling me that most signals are tri-lights, but, tri-light in this case refers to the fact that the three lenses are arranged in a triangular fashion.
The picture at the top of the page is in Havre de Grace MD, on Amtrak's Northeast Corridor, SB as you come off the Susquehanna River bridge, notice the signal uses LED's! More below.
