Remote railway container locking system

摘要

A system for issuing instructional signals to individual cars of a train for causing actuation of a device such as a container locking device of the individual car. A plurality of instructional signal lines and a plurality of feedback lines extend through each car in a direction parallel to the direction of travel of the car, the number of lines being at least as great as the number of cars in the train. The one ends of the lines are connected to terminals at one end of each car in positional correspondence with the lines, and the other ends of the lines in each car are connected to terminals offset by one from the terminals in positional correspondence with the respective lines. The other end of the line on one edge of each array of the plurality of lines extends across the array and is connected to the terminal in positional correspondence with the line on the other edge of the array. The terminals in adjacent cars are connected. Instructional signal receiving relays in each car are coupled to the line on the one edge of each array, and the device for carrying out a desired function, such as locking of container in each car, is coupled to the instructional signal receiving relays for operation in response to energization of the relays. An order fulfilled signal transmitting relay in each car is coupled to the line on the one edge of each array and is actuated upon completion of the desired function. With this arrangement, the cars in the train can be shifted in the train or their direction reversed and the signal lines can still be used to transmit a signal to a given car in the train.
