Hopper car discharge gate seal assembly

A railcar comprising:

• a hopper;
• a discharge assembly coupled to the hopper, the discharge assembly comprising:
• a discharge gate operable to move from a closed position that restricts a lading from discharging through the discharge gate to an open position that permits the lading to discharge through the discharge gate;
• a first sloped side sheet longitudinally extending above the discharge gate when the discharge gate is closed;
• a first gasket bracket coupled to the first sloped side sheet, wherein the first gasket bracket extends longitudinally along a bottom end of the first sloped side sheet;
• and
• a first seal gasket positioned between the first sloped side sheet and the first gasket bracket, the first seal gasket having a straight section and a rounded section;
• wherein:
• the first gasket bracket is mounted on top of the first sloped side sheet;
• the first seal gasket is positioned above the first sloped side sheet and underneath the first gasket bracket, such that a portion of the rounded section of the first seal gasket is left beyond the bottom end of the first sloped side sheet and the bottom end of the first gasket bracket, and
• the first seal gasket creates a seal between the first sloped side sheet and the discharge gate such that a weight of the lading increases the seal.
