A vehicle control system and method include one or more processors that determine that a vehicle has or will have insufficient energy to power a propulsion system of the vehicle under a first set of operational settings to move the vehicle from a first location to a designated second location that is outside of an unpowered segment of a route along which the vehicle moves. Responsive to determining that the vehicle has or will have insufficient energy, the one or more processors change one or more of a throttle setting or a brake setting of the vehicle to operate the vehicle under a second set of operational settings while the vehicle moves within a powered segment of the route.
