摘要：A door position indicating mechanism for use with a railroad car. The mechanism includes a shaft which extends across the longitudinal direction of the car. An offset section of the shaft has a roller which contacts a lever which is shifted by an air cylinder when operating the door mechanism. At least one counterweight biases the roller into constant contact with the door operating lever. Indicators are mounted on either end of the shaft such that the position of the doors can be noted from either side of the railroad car.
