Abstract
An improved automobile transport railway car that is constructed from noncorroding materials adjacent to load carrying areas and that is enclosed by doors on both ends of the car. In the case of the articulated cars, a bellows assembly encloses and spans the ends of adjacent units. The car may be provided with two or more decks and has walls and a roof preferably constructed from nested, pultruded sections that are light in weight and are non-corrodible.
Claims15
An improved articulated railway car having at least a first end unit and a second end unit interconnected with each other by pivotal couplers, each unit having a front, rear and two sides forming a hollow interior for transporting automotive vehicles and comprising:
- a pair of spaced tracks for movably supporting each unit on railway tracks;
- a center sill having a first end supported by one of said trucks and a second end supported by the other of said trucks;
- a plurality of cross-bearers spaced along and disposed generally perpendicular to and connected to said center sill, said cross-bearers having free ends remote from said center sill;
- a plurality of side wall support posts extending generally vertically from and mounted on each said cross-bearers;
- a plurality of generally vertically disposed hollow wall sections forming side walls connected to said posts, each of said side walls having a lower edge adjacent to said cross-beams, an upper edge, and front and rear edges adjacent the front and rear of each unit, respectively;
- each of said hollow wall sections comprising a composite material pultrusion having interior and exterior panels with a plurality of vertical spacers holding said panels in spaced relationship, and wherein each of said pultrusions further comprises first and second ends formed so that the first end of a pultrusion mates with the second end of another pultrusion;
- said side wall support posts disposed intermediate selected pairs of said spacers;
- a roof extending from the front to the rear of each unit and connected to the upper edges of said side walls;
- an end closure located at one end of said first end unit and at one end of the said second end unit and connected to the front and rear edges of said side walls and to said roof;
- a plurality of expandable and collapsible bellows substantially spanning and enclosing adjacent ends of said first and second end units, said bellows connected to adjacent ends of each unit;
- said bellows further comprising a plurality of flexible, generally U-shaped members having a configuration to match the adjacent ends of each car;
- a plurality of elongated channels sized to receive free ends of said U-shaped members;
- means for connecting said channel members to said free ends of said U-shaped members;
- and
- each of said U-shaped member including flexible reinforcing metal wire.

An improved articulated railway car for transporting automotive vehicles including a plurality of units comprising:
- a frame and a floor for each unit;
- a pair of end units, each of said end units having first and second ends, a plurality of vertically extending, spaced side wall support posts on said frame between said first and second ends, said end units supported for movement on railway tracks by trucks located adjacent to said first and second ends;
- at least one intermediate unit pivotally connected with the first ends of said end units, said intermediate unit being supported for movement on railway tracks by sharing the trucks located at the first ends of said end units and having a plurality of vertically extending, spaced side wall support posts on said frame means;
- each end unit and each intermediate unit including side walls and a roof constructed from hollow sections;
- each of said side wall hollow sections comprising a composite material pultrusion having interior and exterior panels with a plurality of spacers holding said panels in spaced relationship, and wherein each of said pultrusions further comprises first and second ends formed so that the first end of a pultrusion mates with the second end of another pultrusion;
- said roof further comprising spaced interior and exterior roof panels with connecting means joining the roof means to said side walls;
- and
- said hollow sections which form said side wall means being disposed over and connected to said side wall support posts;
- a second floor located between said first-mentioned floor and said roof and coextensive with said first-mentioned floor;
- a first support connected to said side wall posts for positioning said second floor in said car;
- a plurality of expandable and collapsible bellows substantially spanning and enclosing adjacent ends of said units, said bellows connected to adjacent ends of each unit;
- a plurality of flexible, generally U-shaped members having a configuration to match the ends of each unit;
- a plurality of elongated channels sized to receive free ends of said U-shaped members;
- means for connecting said channel members to said U-shaped members;
- each said U-shaped member includes flexible reinforcing metal wire;
- and
- said roof further comprises a plurality of hollow roof composite material pultrusion sections having interior and exterior panels with a plurality of spacers holding said panels in spaced relationship, and wherein each of said roof pultrusions further comprises first and second ends formed so that the first end of a pultrusion mates with the second end of another pultrusion;
- and
- said hollow wall sections, said bellows, said first floor, said second floor and said roof cooperating to provide a weather-proof and vandal-proof covering that permits movement between said units,
