摘要： A door assembly for a railcar includes a sliding system and a latching system. The sliding system is operable to slide the door to a side of the entrance of the railcar to provide an opening path to an entrance of the railcar. The sliding system comprises one or more rollers used for sliding the door. The latching system is operable to plug the door to the railcar such that the door moves inward toward the railcar, and unplug the door from the railcar such that the door moves outward from the railcar. The latching system comprises a lever operably coupled with two or more gears. The lever turns a particular number of rotations in a first direction to plug the door to the railcar. The lever turns the particular number of rotations in a second direction to unplug the door from the railcar.
