Abstract: A system for aerating and controlling the temperature of ladings, such as perishable commodities, in a covered hopper railway car, includes a blower communicating with the interior of the car through the side sills and side stakes, formed as conduits, and through perforations in the side stakes and in slope plates of the hoppers. To complete the air circuit, there are also provided ducts at the top of the car. The flow of air may be reversed and the air may be heated or cooled.
