Abstract
An adjustably positioned container guide and spacer device to be mounted on a side wall defining a container well of a railroad car for receiving intermodal cargo containers of different widths, the device acting as a guide during loading of a container into the container well, and acting to restrain a container, particularly one narrower than the width of the container well, to prevent such a container from moving laterally too far once it has been placed within the container well. A sloping guide surface and a blunt, convexly curved spacer nose surface of the guide body are presented so as to guide a container to the proper location within a container well, and the nose surface thereafter prevents the container from moving an excessive distance laterally within the container well when the guide body is latched in the correct one of the available inner and outer positions, as determined by the width of the container. A latch bar permanently but movably held in the guide body is ordinarily held in a selected latching position by the force of gravity, but is upwardly movable to disengage the latch and permit relocation of the guide body.
