ABSTRACT:
A railroad car for transporting vehicles such as automobiles and trucks has a pair of door assemblies which close each end of the railroad car. The lower end of the door assemblies are guided in a track and the track has vertically retractable sections located where the vehicle tires roll so as to provide added load height when the car ends are open and vehicles are being loaded or unloaded. An embodiment with a pivotal, counterweighted Z-shaped member upon which the retractable track section is mounted is disclosed along with an embodiment utilizing a vertically displaceable tubular member and a coil spring.
