Abstract
The present invention provides a portable remote control device adapted for transmitting command signals to a locomotive control device located onboard a locomotive. The command signals are indicative of a command to be executed by the locomotive. The portable remote control device is adapted for transmitting the command signals over either a remote communication link or a proximity communication link at least in part on the basis of a link selection signal received by the remote control device, wherein the link selection signal is indicative of the proximity of the portable remote control device to the locomotive. The remote communication link and the proximity communication link are distinguishable based on their range of communication. More specifically, the remote communication link permits the remote control device and the locomotive control device to communicate over a greater distance than the proximity communication link.
