Abstract
A locomotive control system includes an on-board controller responsive to a time signal received from a remote source for outputting a first polling signal at a time determined with reference to the time signal. A first remote controller is responsive to the polling signal for outputting a first control signal during a first interval of time. The on-board controller is responsive to the first control signal for controlling one or more functions of the locomotive. The locomotive control system can also include a second remote controller responsive to a second polling signal output by the on-board controller at a time after the first interval of time determined with reference to the time reference signal for outputting a second control signal during a second interval of time. The on-board controller is also responsive to the second control signal for controlling one or more functions of the locomotive.
