ABSTRACT A railway car door of the type including a pair of pipes and cranks rotatably secured to the door. An operating mechanism is provided for rotating the pipes and cranks and includes a shaft rotatably supported on the door with activating means in the form of a handle secured to the shaft. A transmission means is provided which is supported on the door interconnecting the operating mechanism with the pipes and cranks. Upon rotation of the shaft in response to operation of the activating means, a corresponding rotation is imparted to the cranks and pipes to provide a selective lateral movement of the door into and out of an opening in the side of a railway car. The railway car is equipped to have internally projecting cargo or lading restraining members selectively attached and removed from the inside of the railway car side wall adjacent to the opening. Filler members are provided which are removably attached to the door. The filler members project into the car by an amount substantially equal to the internal projection of the cargo restraining members. Means are provided for selectively increasing or decreasing the amount of rotation of the pipes and cranks possible so that when the filler members are attached to the inside of the door, the pipes and cranks can move a greater rotational distance to consequently move the door laterally out of the opening a first, greater distance and thereby permit the filler members to clear the side wall or an adjacent door of the railway car. When the filler members are removed, the cranks and pipes are permitted to rotationally move a lesser distance to consequently move the door, without filler members attached thereto, a second, lesser distance laterally out of the opening and clear of the side wall or an adjacent door of the railway car. Adjustable door stop means are also provided for positioning the door and for protecting the door and a second, railway car door, which may be adjacent thereto, from damage by impact with each other. The adjustable door stop means includes an adjustable door stop member selectively secured to the door in a first and a second position. In the first position, the adjustable door stop member protects the doors from damage by impact with each other when the second, adjacent door is moved laterally out of the opening the first, greater distance while allowing the second adjacent door to move along the side wall in a direction away from the other door. In the second position, in which the adjustable stop member is in an inverted position with respect to its first position, the adjustable door stop member is stored and remains readily accessible when next needed for protection of the filler supporting doors from impact with each other.
