Abstract: A storage structure includes a plurality of sequentially arranged positions, each position for holding one order at a time. One of the positions is an end position from which an order is to be taken up for provisioning. Each order in a position moves to the next sequential position toward the end position, as the next sequential position becomes empty and available. The positions are organized into a first section and a second section. The first section is distal from the end position and includes at least one position. The first section receives orders from a first order delivery system into a receiving position. The second section is proximate to the end position and includes at least one position. The second section receives orders from a second order delivery system into a receiving position.

Abstract: Disclosed is an operator warning system for use in connection with a locomotive having a horn system with a horn activation actuator and a horn device for producing a noise. The operator warning system includes an onboard computer system with a database having grade crossing data and locomotive data thereon. The onboard computer system is in communication with the horn system. The operator warning system also includes a warning device for providing an audio, visual and/or tactile indicator to an operator of the locomotive based upon the grade crossing data, locomotive data and/or actuation condition of the horn activation actuator. A method for improving locomotive operator vigilance is also disclosed.
