A method includes defining a pre-load zone that has reliable communication along a route. The pre-load zone is associated with a trip of a vehicle traveling along the route. A starting location of the trip is located outside of the pre-load zone. The vehicle is configured to enter the pre-load zone and exit the pre-load zone prior to reaching the starting location of the trip. The method includes receiving a trip request message that identifies the pre-load zone from the vehicle after the vehicle enters the pre-load zone and prior to the vehicle exiting the pre-load zone. The method also includes sending a trip response message to the vehicle that the vehicle receives prior to exiting the pre-load zone. The trip response message includes trip data specific to the trip that is selected based on the association between the pre-load zone and the trip.
