Abstract
Systems, methods, and non-transitory machine-readable media for tracking the state of a rail car are disclosed. In one or more example embodiments, a device may use sensors such as a spring height sensor or a time of flight sensor to determine a status of a load car, which may be associated with a location. The system may determine a delivery event at the location. This data may be correlated with spring usage data.
