Abstract
An improved railroad communication system configurable to comply with newly proposed FRA regulations and further configurable to addresses the concern of communications conflicts is provided. The railroad communication system includes a first radio communication system operating in a first frequency band of about 450 MHz band for communication with a locomotive. The system further includes a second radio communication system operating in a second frequency band selected to be different from the first frequency so as to avoid interference with the first radio communication system for communication with the locomotive. A processor on the locomotive enables the locomotive to selectively respond to the designated control signals so that operation of the locomotive will respond only to the appropriate control signals.
