<p>Baffles are provided in transportation hoppers to solve the problem of upper bulk lading exerting pressure and causing damage to lower bulk lading in the hopper by reducing load density of the lading. The baffles are preferably inclined with respect to the horizontal. More than one layer of baffles may be provided. Supports for the baffles are preferably fixed to the sides and/or roof of the transportation hopper. The baffles may be provided with openings to facilitate circulation of conditioned air through the hopper. The baffles may be provided with larger openings which facilitate loading the hopper. The baffles also may be provided with doors which facilitate loading the hopper by means of a loading chute. The baffles may be used in a wide variety of transportation hoppers. In a preferred embodiment the transportation hopper is a railway hopper car.</p>
