Abstract

A method of shipping automobiles, railcars for shipping automobiles, and methods of manufacturing railcars for shipping automobiles to enable more efficient shipping of automobiles by facilitating conversion of autorack cars between unilevel, bi-level and tri-level configurations, and/or by providing increased load factors.

First claim

The invention claimed is:

1. A method of converting an enclosed tri-level auto-rack railcar to an enclosed bi-level railcar comprising:
providing a tri-level auto-rack railcar having,
a first deck capable of supporting motor vehicles for transport in commercial rail operation,
a second deck spaced above the first deck by a distance sufficient to provide clearance for vehicles on the first deck, wherein the second deck is capable of supporting motor vehicles for transport in commercial rail operation,
a third deck spaced above the second deck by a distance sufficient to provide clearance for vehicles on the second deck, wherein the third deck is capable of supporting motor vehicles for transport in commercial rail operation,
a roof structure at a height of approximately 20′ 2″,
side walls extending from the first deck to the roof structure, and
end doors that are movable between open positions in which access to the interior of the railcar is permitted, and closed positions in which the interior of the railcar is enclosed to prevent unauthorized access;

and removing the third deck so that the second deck may be used for transport of vans while transporting conventional vehicles on the first deck without adjustment of the height of the second deck;
wherein the overall height of the railcar is approximately 20′ 2″, and the second deck is at a height that enables the second deck to be used for transport of vans while transporting conventional vehicles on the first deck.

2. The method of claim 1 , wherein the first deck is substantially horizontal.

3. The method of claim 1 , wherein the tri-level railcar comprises providing a flat car with a 39½ inch ATR running surface to serve as the first deck.

4. The method of claim 1 , wherein the first and second decks of the enclosed bi-level railcar are removably bolted in place.

5. The method of claim 1 , wherein the enclosed bi-level railcar has a removable, bolted-on roof.

6. The method of claim 1 , wherein each of the first and second decks of the enclosed bi-level railcar is capable of supporting 24,000 lbs.
