Description
Every important and heavily trafficed grade crossing has some kind of visible and/or audible protection for highway vehicles. We are all familiar with the flashing lights, bells and gates but here's a type of signal predominantly used in the Western United States. In this "Wig-Wag" type, the red light and warning disk are on a short pendulum suspended from a horizontal arm that swings (wig-wag) back and forth.
