摘要： An improved railway car body structure is described. One of the features of the box car is that the longitudinal side walls are formed by a plurality of spaced apart vertical side posts which are hat-shaped in cross-section and define a bottom wall portion, opposed side walls and opposed end flanges extending in a common plane. Horizontal structural stiffeners are secured between the vertical side posts. The stiffeners define a recessed wall portion aligned with a recessed formation formed in the opposed end flanges of the vertical side posts. Ferrous sheet members are secured to the side wall and also to the end frames by welds disposed in the recess wall portion of the stiffeners and recessed formation of the vertical posts to form flush, unobstructed, inner side and end walls of the railway car. A new roof structure is also described and incorporates improved skylight designs.

摘要： A low-level freight car for carrying trailers and containers at a low overall height combines a low center sill with relatively light side sill assemblies to provide a rigid structure having low deflection characteristics under the expected buff, draft and vertical load combinations, while keeping overall tare weight to reasonable levels and providing an adequate safety factor.
摘要翻译：用于承载低整体高度的拖车和集装箱的低级货车将低中心梁与相对较轻的侧梁组合相结合，以提供在预期的减速，牵伸和垂直负载组合下具有低偏转特性的刚性结构，同时保持整体重量达到合理水平，并提供足够的安全系数。
