Abstract
A ride-through control system for operating locomotives in a train includes a geographic position sensor configured to generate a signal indicative of a geographic position of a locomotive of a train, and a controller configured to receive the signal indicative of the geographic position of a locomotive and compare the geographic position of the locomotive with one or more pre-determined geographical locations or regions previously identified as geo-fences. The controller may also be configured to receive one or more locomotive operational signals indicative of at least one of an operational parameter, a fault, and a maintenance request associated with the locomotive, determine whether the geographic position of the locomotive coincides with a geo-fence characterized by conditions that may affect the ability of the locomotive to meet a trip objective if the locomotive were to slow below a threshold speed within the geo-fence, and generate a ride-through control command signal to prevent the locomotive from slowing below the threshold speed within the geo-fence based on at least one of the one or more locomotive operational signals and a user permission level.
