• wherein:
• each of the first plurality of end doors is adjacent to a respective deck of the first plurality of decks, and
• each of the plurality of first end doors is configurable between a vertical orientation and a horizontal orientation such that each of the first plurality of end doors aligns with its respective deck of the first plurality of decks when in its horizontal orientation;
• a second railcar comprising:
• a second plurality of decks disposed at different levels within the second railcar;
• a second plurality of end doors disposed at a first end of the second railcar,
• wherein:
• each of the second plurality of end doors is adjacent to a respective deck of the second plurality of decks, and
• each of the second plurality of end doors is configurable between a vertical orientation and a horizontal orientation such that each of the second plurality of end doors aligns with its respective deck of the second plurality of decks when in its horizontal orientation;
• and
• wherein when a first end door of the first plurality of end doors of the first railcar is in its horizontal orientation it aligns with a second end door of the second plurality of end doors of the second railcar when the second end door is in its horizontal orientation;
• and
• wherein when a third end door of the first plurality of end doors of the first railcar is in its horizontal orientation it aligns with a fourth end door of the second plurality of end doors of the second railcar when the fourth end door is in its horizontal orientation.
