Railcar for transport of steel coils with removable bi-level roof

A 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 a first interior surface and a second exterior surface;
• a removable cover assembly comprising a removable bilevel roof including a first section having a first height, a second section having a second height, and a third section having a third height, wherein the second section is between the first section and the third section, wherein the second height is less than the first height and the second height is less than the third height, and the first section and the third section are proximate the first and second ends of the railcar frame;
• and
• a plurality of troughs along the railcar frame for transporting a metal coil in each trough,
• each trough comprising:
• (a) a first inner coil receiving plate with laterally opposed side edges and longitudinally opposed end edges, the first inner coil receiving plate having an inner surface and an outer face;
• (b) a second inner coil receiving plate with laterally opposed side edges and longitudinally opposed end edges, the second inner coil receiving plate having an inner face and an outer face;
• and
• (c) a stiffener substantially coupled to the outer face of each of the first and second inner coil receiving plates and substantially coupled to the first interior surface of a side wall and the first interior surface of an opposite side wall;
• wherein, each trough is welded to the first interior surfaces of the side walls.
