A traffic crossing warning device is provided. The device includes a beam transmitter for transmitting a beam such as an IR beam, and a beam sensor in electrical communication with a signal processor for sensing the IR beam. In addition, the device includes a multimedia warning beacon, and a mounting device for supporting the beacon adjacent a roadway intersection. The warning beacon is activated when the beam sensor senses that the beam is not being received for a predetermined period of time. In one aspect, the warning beacon has a warning light, a speaker for delivering an audible signal, and a display for providing a written warning. A method for warning motorists of the presence of an oncoming locomotive object such as a train using the warning device is also provided.
