Coal fly-ash railway hopper car with 70 degree minimum slope and end sheet angle and longitudinal dual purpose loading hatch

摘要

A dual-purpose railway hopper car is constructed so that it is capable of holding, handling and hauling both coal and fly ash on different trips by virtue of having a plurality of quick opening hopper doors which are sealed to prevent leakage of fly ash when closed, highly sloping active walls, a covered top with a wide longitudinal hatch for loading coal, which wide hatch carries a smaller circular hatch for pneumatically loading fly ash. The coal hatch is operated by air cylinders from a quick connect coupling at ground level. A center sill covers the hopper door operating linkage.
