Abstract

According to some embodiments, a railcar comprises a door, and the door comprises an inside panel and a plurality of ladder rungs coupled to the inside panel arranged in a vertical sequence. The railcar further comprises a folding ladder apparatus comprising a first ladder rung and a second ladder rung. The folding ladder apparatus is pivotally coupled to the inside panel and operable to pivot in a vertical direction between an up position and a down position. When the door is in an open position and the folding ladder apparatus is in the down position, the second ladder rung extends below a bottom of the door facilitating access to the railcar. When the folding ladder apparatus is in the up position, the first ladder rung and the second ladder rung are vertically offset from the plurality of ladder rungs coupled to the inside panel of the door.
