Abstract
A railway car (10) is provided. Railway car (10) comprises hopper assemblies (18) having floor panels (22, 24, 26, and 28) that are angled at approximately 40.degree. or less. Floor panels (22, 24, 26, and 28) are fabricated from an aluminum material such that cargo may slide down floor panels (22, 24, 26, and 28) and exit hopper assembly (18) through an outlet (20) with relative ease while maximizing volume. Aerodynamic side posts (54) and improved side plates (58 and 60) which prevent water from entering hoppers (18) are also provided. An improved hatch (56), having first and second coaming portions (88 and 86) that are formed by a single extrusion process, is also presented.
