Abstract: Train position is sensed using a position sensing unit having plurality of position sensors arrayed in the direction of train travel. The sensors respond to the presence and absence of a detection element on each train car, the detection element being longer than the spacing between adjacent position sensors. A confirmed count of a train car passing the position sensing unit requires detection of a series of related position sensor activations and deactivations. Alternately, the position sensing unit senses data tags on the train cars, reading unique identifiers therefrom. A list of identifiers corresponding to the car order is stored and compared to the identifiers read in order to determine train position.

Abstract: A bulk material handling system and method use a horizontal boom frame supporting a conveyor mechanism for bulk material that is slidable relative to the horizontal boom frame. The conveyor mechanism is positioned such that, with bulk material received at a fixed location, or loading axis, on the horizontal boom frame, a portion of the conveyor mechanism will always be positioned to receive bulk material. The horizontal boom frame can also be made rotatable about the loading axis. By rotating the horizontal boom frame and advancing or withdrawing the conveyor mechanism, the discharge point for bulk materials relative to the loading axis can be altered radially and angularly without interrupting the flow of bulk materials through the system. A supply bridge assembly can be employed to bring the bulk materials to the loading axis of the boom.

Abstract: A train is driven by drive stations positioned along a track for frictionally contacting side plates on the train. The drive speed is controlled in response to sensors located at each drive station sensing a position of a wheel and a side plate for confirming a presence of the train. A start command is transmitted from the drive station driving the train to a second drive station downstream when a lead car is within a preselected distance from the second drive station. The drive station at the second drive station is quickly accelerated to a target speed for synchronizing the first drive station with the second drive station. After receiving the train, the second drive station then transmits a stop command to the first drive station for fast decelerating the drive station to a stop.
