Abstract
Apparatus for securely fastening both of a pair of doors, such as the doors at an end of an auto rack railroad car, in a closed condition, using a single lock. A hasp mounted on one of the doors can be locked in a securing position in which locking members prevent the locking rod handles from being removed from receptacles that hold the locking rod handles with the locking rods in door-latching positions when the doors are closed. The hasp thus prevents the locking rod handles from being moved to rotate the locking rods from their door-latching positions. A single lock can prevent the hasp from being moved and thus prevent both locking rod handles from being moved.
