Abstract
Abstract An aluminum hopper car having a high-pitched roof defined by sheeting mounting carlines connected between box-shaped sideplates and the coaming defining a continuous trough hatch opening, the carlines being in transverse alignment with box section side posts and reinforcing partition sheets and the bolster web, a horizontal shear plate lying in the plane of the horizontal portions of the side and end sills connecting with said bolster web and end slope sheet to define a closed torque box arrangement, said slope sheet comprising a plurality of sections of variable thicknesses to accommodate load requirements, the shear plate and slope sheets being assembled by butt welding techniques.
