Railroad car with retractable closure track held down by bridge plate

A railroad car for transporting four-wheel vehicles such as automobiles and trucks, comprising:

• a floor and two side walls defining an interior space and terminating in an opening at each end;
• an end closure at each end of the car adapted to be displaced between a closed position overlying the end opening and an opened position which provides access to the entire end of the car;
• an elonagated closure support member at each end of the car disposed within the car interior in a horizontal plane;
• the closure support member having a front run lateral to the car and a side run along each car side wall;
• the closure comprising a pair of door assemblies;
• each door assembly having a forward vertical end and a rear vertical end;
• means vertically suspending the door assemblies from the closure support member so that the door assemblies are movable horizontally toward each other into closed position to close the car end with the forward ends of the door assemblies in abutting position to each other in the middle of the closure support member front run, and away from each other into open position with each door assembly supported on a closure support member side run;
• a guide track, for the door assemblies, disposed within the car interior in a horizontal plane and mounted to the car floor and extending upwardly therefrom;
• the guide track having a front run lateral to the car and a side run along each car side wall;
• guide means carried by the bottom of the door assemblies engaging the guide track to guide the door assemblies along the track when they are moved to open and close the car end;
• the guide track front run having two spaced apart retractable track sections movable up and down from an up position wherein the track sections project above the floor level to a down position wherein the track sections are at a height not above the floor level;
• bridge plate support means mounted on the car adjoining each retractable track section;
• means maintaining a track section in said down position when a bridge plate is engaged with the adjoining bridge plate support means;
• each of the retractable track sections in said down position being positioned to be rolled over by the wheels on one side of four-wheel vehicles transported by the railroad car;
• and
• means forcibly maintaining the retractable track sections in said up position when the door assemblies are closed.
