Abstract

An air flow conduit (98) and a related plenum (80) for distributing conditioned air from a refrigeration and heating unit (64) on an end (44) of a railroad freight car (20) into a cargo space (53) within the car (20). A deflector directs a flow of air upward into an inlet end of the plenum (80) and allows the flow to expand gradually within the plenum, smoothing the flow of air within the plenum so that it continues effectively at sufficient rates over the length of the car (20).
