RETRACTABLE FRONT DOOR STOP

摘要

This invention is a front door stop arranged to retract inside the clearance limits of a railroad car when the car's plug-type door is in a closed position. When the plug door is in open position, the front door stop is designed to extend beyond the clearance limits of the car so as to present a striking surface to effectively limit the travel of the door along the door track. The retractable front doorstop is also used to position the door for lateral movement into the door opening in the car side.
