Door Assembly for Railcars

A railcar, comprising:

• a door;
• and
• a door assembly operably coupled with the door, comprising:
• a sliding system operable to slide the door to at least one side of the railcar to provide an opening path to an entrance of the railcar when the door is opened, wherein the sliding system comprises one or more rollers used for sliding the door;
• and
• a latching system operable to:
• plug the door to the railcar such that the door moves inward toward the railcar when closing the door;
• and
• unplug the door from the railcar such that the door moves outward from the railcar when opening the door, wherein the latching system comprises:
• a first gear with a first radius;
• a second gear operably coupled with the first gear, having a second radius;
• a lever operably coupled with the first gear and the second gear, wherein:
• the lever is operable to turn a particular number of rotations in a first direction to plug the door to the railcar;
• the lever is operable to turn the particular number of rotations in a second direction to unplug the door from the railcar;
• and
• a ratio of the first radius over the second radius is determined such that the lever is operable to turn when a force within a target force range is applied to turn the lever the particular number of rotations.
