  • Railroad communication system
    Patent number: 6854691
    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.
