Multi-bunk railcar for transport of metal coils

A railcar with a plurality of transverse bunks along the car body for transporting a metal coil in each transverse bunk, the railcar comprising:

• a longitudinally extending railcar frame with first and second opposed ends;
• a pair of side walls extending the longitudinal length of the railcar and secured to the frame on opposed sides of the railcar, the side walls having an interior and an exterior surface;
• each transverse bunk comprising:
• (a) a bottom plate with first and second laterally opposed side edges and longitudinally opposed end edges as well as a bottom plate upper surface and a bottom plate lower surface, the bottom plate extending as a horizontal segment from the second laterally opposed edge to a first line of inflection upwardly to a second line of inflection and extending more vertically to and terminating at the first laterally opposed edge;
• (b) a side plate with first and second laterally opposed side edges and first and second longitudinally opposed end edges as well as side plate upper surface and a side plate lower surface, the first laterally opposed side edge of the side plate slightly lapping the second laterally opposed side edge of the bottom plate, the side plate extending upwardly proximate the lap from a first line of inflection to a second line of inflection whereupon the side plate extends more vertically before terminating at the second laterally opposed side edge;
• and
• (c) a transverse bunk reinforcing member with longitudinally opposed end edges, a separate reinforcing member welded to and spanning the entire longitudinal length of the lower surface of the bottom and side plates;
• wherein, the longitudinally opposed end edges of the bottom plate, side plate and bunk reinforcing members are welded to the interior surfaces of the sidewalls.
