ABSTRACT:
A method and drawbar apparatus for engaging a latch of and manually moving a bulkhead door in a railroad boxcar. The drawbar has an elongate bar with a T-shaped handle at one end and a generally arcuate hook at the other end. In use, the bar retains the latch handle in a released position and applies a manual force to the bulkhead to move it. The T-shaped handle is distal from the bulkhead to safely keep a worker's digits, torso and feet from the door and boxcar sidewall. To facilitate easy and smooth movement of the bulkhead door, the hook removably engages and interlocks with the latch or a latch shaft so that force is applied to the bulkhead door adjacent its center of mass.
