1. A method comprising:
determining whether a ratio of a lateral force exerted by one or more wheels of a vehicle system on a route to a vertical force exerted by one or more wheels of the vehicle system on the route increases to a value that exceeds a designated threshold; and
reducing the ratio of the lateral force to the vertical force exerted by the one or more wheels of the vehicle system on the route to a value less than the designated threshold by changing an operation of the vehicle system,
wherein the operation of the vehicle system is changed by one or more of:
changing a torque imparted on an axle of the vehicle system by one or more motors,
changing a tractive effort generated by a motor-axle combination of the vehicle system,
changing a wheel creep of a set of wheels coupled with an axle of the vehicle system, or
preventing application of a friction-modifying substance to the route by a wheel adhesion control system disposed onboard the vehicle system.
