Abstract
A railway car for transporting pulverulent lading includes a fluid-tight container, slope sheets mounted within the container defining two troughs leading to a sump in the lower portion of the container, two aligned permeable conveyors in the bottom of each trough, an apparatus for alternately aerating each permeable conveyor in each trough for fluidizing the lading to facilitate movement thereof into the sump. Discharge valve structure is provided below the sump for pneumatically unloading the container pipe for pressurizing the space between the slope sheets and the container, and a pipe interconnecting the top of the container and the discharge valve structure for conveying air from within the container to the discharge valve structure during unloading of the container, are also provided.
