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 a bi-level auto-rack railcar to a tri-level auto rack railcar, the bi-level auto rack railcar comprising a first deck, a second deck above the first deck, a roof structure, side walls extending from the first deck to the roof, and end doors extending between the first deck and the roof, the method comprising:
removing the roof structure;
adjusting the height of the second deck;
lowering a third deck into the railcar above the second deck using an overhead crane; and
replacing the roof.

2. A method of converting a bi-level auto-rack railcar to a unilevel railcar, the bi-level autorack railcar comprising 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, the second deck also being capable of supporting motor vehicles for transport in commercial rail operation, a roof structure, side walls extending from the first deck to the roof, and end doors extending between the first deck and the roof, the end doors being movable between open positions in which access to the railcar interior is permitted, and closed positions in which the interior of the railcar is fully enclosed to prevent unauthorized access, the method comprising:
removing the roof structure to facilitate crane access to the railcar interior;
removing the second deck from the railcar using a crane; and
replacing the roof to provide an interior space that is capable of accommodating and enclosing vehicles of a height greater than the distance by which the second deck was spaced above the first deck.
