ABSTRACT:
A refrigerated railcar having a bunker for holding CO.sub.2 snow generated by a spray manifold temporarily hooked up to a supply of liquid CO.sub.2, the bunker allowing the gaseous CO.sub.2 sublimated from the formed snow to pass down through vents and into an improved underfloor flow channeled floor which provides a maze-like structure to cool an underside of the cargo. Additionally, an improved insulated manifold pipe hanger is described. Additionally, an improvement in the venting arrangement of the bunker area and an improved configuration of the manifold orifices to provide a more evenly deposited snow thickness throughout the bunker during charging is described.
