ABSTRACT:
A discharge hopper rail car (10) comprises a hopper body (14) mounted on a chassis (12) which is itself supported on flanged wheels (20). The body (14) includes a discharge opening in a lower part thereof and a door structure (16) pivotally mounted on the body (14) and displaceable between a closed condition in which the opening is closed by the door structure (16) and an opened condition to permit discharge of the contents of the body (14). The door structure (16) forms a basin for collecting both liquids and fines leaking from the opening when the door structure (16) is in its closed condition.
