Abstract
A well car for carrying shipping containers has a pair of end structures supported by railcar trucks, a pair of first and second spaced apart side beams extending between the end structures and a well defined therebetween. Container support cross-members are mounted between the side sills in a position to support an end of a shipping container load carried within the well. An array of elongate members is provided to divide the opening into smaller spaces and to prevent excessively large openings from being left. The elongate members can have different forms, whether rigid hollow structural sections, rods, or cables. The arrays of elongate members are oriented at oblique angles along the railcar body.
Claims30
A railroad well car body unit comprising:
- a pair of first and second side beams, said side beams extending lengthwise between first and second railcar end sections mounted to railcar trucks for rolling motion in a longitudinal direction along railroad car tracks;
- said railroad well car having a well defined between said side beams and said first and second railcar end sections;
- first and second container support cross-beams extending cross-wise between said first and second side beams;
- an intermediate container support cross-beam located between and spaced from said first and second container support cross-beams;
- said first and second container support cross-beams having container indexing fittings upon which to locate shipping containers;
- an array of struts extending between, and mounted to, said first and second side beams;
- said array of struts including at least a first strut and a second strut;
- said first strut having a first end mounted to said first side beam and a second end mounted to said second side beam;
- and
- said first strut being angled obliquely relative to said longitudinal direction.
