A method for enhancing an initial tension by changing a wound direction of a coil spring. The curvature of the track is determined by dividing a yaw rate by a translation rate, and the wheels are oriented on the basis of a setpoint steering angle which is calculated by multiplying the track curvature by one-half the distance between the two axles of the truck. Each of the geo-location paths includes the identified transit point. The data store includes data representative of inputs provided by authorized users who are authorized to operate the depository.
