Title: RAILROAD CROSSING WARNING SYSTEM
Abstract:
A railroad crossing warning system includes a beam emitter for generating a focused beam of energy, and a receiver for receiving the focused beam of energy. A pair of weatherproof housings secures the emitter and receiver diagonally at a railroad intersection. A base station is communicatively linked to the beam emitter and the receiver, and a base station communication unit transmits an obstruction warning to an approaching train.
