发明名称 Railway freight car
摘要 A railway car comprises a center sill with a crossbearer, webs and end bolsters extending across thereof. A light side stiffener interconnects the projecting ends of said webs and spans between the bolster and the crossbearer. A shear plate covers a trapezoidal end frame extending from the bolster. The frame includes inclined braces buttressing a pair of cantilevered brackets projecting toward and horizontally overlapping similar brackets of the adjacent car.
