CA 2416090
A tri-level railcar wherein the B deck is fixed along its entire length, rather than having hinged end sections, so that the B deck contributes to the strength and rigidity of the car. To provide sufficient clearance in the A1 and A5 positions, the B deck is positioned at a higher elevation than in conventional prior art auto rack cars. Clearances above each of the three decks may be approximately equal. High cambered decks are preferably employed at both the B and C level. The overall height of the railcar is preferably about 20'2". All three decks may be continuously loaded and unloaded without the need to stop loading and unloading to pivot the B deck end sections. The ability of the B deck to function as a structural member of the railcar from end to end may eliminate the need for cross braces, i.e., brace bays, as included in typical prior art tri-level auto racks. The side wall posts may all be of the same or similar cross-section.
