摘要： A cast metal sideframe for use in a railway car truck has a spring seat for supporting the springs of a spring set. The sideframe is molded using a core that includes a portion for defining the exterior surface of the spring seat. The core can be a single piece or multi-piece core. The spring seat includes a plurality of aerodynamically-shaped spring retainers formed on the top face spring seat. The aerodynamic shape of the spring retainers reduces the tendency for sand to swirl and create voids during formation of the sand core that is used to mold the sideframe. The aerodynamic shape may include forming at least some of the side walls of the spring retainers at an obtuse angle with the top face of the spring seat. The spring retainers may have concave top faces so as to reduce the volume of material comprising the spring retainers. Reducing material volume is beneficial for reducing shrinkage during cooling of the sideframe, thereby reducing the tendency for separation, tears and cracks to form on the top surface of the spring retainer.

摘要： A long travel constant contact side bearing for railway cars provides better handling characteristics, achieving improved tracking and curving through use of various combinations of features. Such a long travel side bearing is able to meet recent stringent American Association of Railroads standards, such as M-976. Lowered spring rates, preferably less than 6,000 lb/in., help with stability and reduce set-up sensitivity. Reduced cap and base dimensions and spring design help achieve travel of at least ⅝″. A visual inspection windows allows ready inspection. Increased service life and wear characteristics are obtained by addition of hardened wear surfaces, improved tolerances, changes to Grade E steel, increase of top contact surface flatness and coped top surface peripheral edges. Standardized sets of spring components can be mixed and matched, requiring fewer specialty parts. Interchangeability of improper components can be prevented by a combination of keying features and/or spring lockout features.

摘要： A novel method and apparatus for installing and securing auto rack side panels, either during manufacture of the auto rack railway car, or during refurbishment of the car, where covers are placed over components which clamp the panel corners. In a preferred embodiment of the invention wherein end portions of elongated dust closure plates are employed to clamp side panel corners against brackets to prevent metal-to-metal contact between the end portions of the dust closure plates and the side panel corners engaged by the end portions thereof, plate covers are installed over the end portions of the elongated dust closure plates so as to be disposed between the end portions of the dust cover plates and the panel corners, to avoid abrasion and rusting as a result of friction. In accordance with a further feature of a preferred embodiment of the invention, there are provided a plurality of bracket covers which fit over the brackets between the brackets and the panel corners engaged thereby to avoid abrasion and rusting resulting from friction with the brackets.

摘要： A pivot plate assembly for supporting vehicles over the articulation between pivotably interconnected railway car units, and allowing rolling transport of vehicles from one railway car unit to the next. Platforms are pivotably attached to respective railway car units adjacent their interconnected ends. A vehicle has its front end portion secured to one of the pivotal platforms and its rear end portion secured to the other platform while the platforms are oriented collinearly with respect to one another. The vehicle thereby maintains the pivotal platforms collinear with one another as the railway car units pivot with respect to one another. Accordingly, the pivotal platforms remain substantially stationary with respect to the vehicle supported thereon throughout pivotal movement of the railway car units to stably support the vehicle straddling the articulation between pivotably interconnected railway car units during transport. Bridge plates are slidably engaged to both of the railway car units and span the pair of pivotal platforms to allow rolling transport of vehicles over the articulation from one railway car unit to the next. The platform assembly remains in place throughout loading, transport, and unloading of vehicles. Each of the pivotal platforms and bridge plates may comprise one or more molded polymeric structures having a ribbed bottom surface to provide light weight, high strength, and durability.

摘要： An improved three-piece truck system for railroad cars provides long travel side bearings for improved stability, a “wide” friction shoe design or equivalent to improve sideframe and bolster squareness, a resilient pedestal pad for improved curving performance and enhanced wear resistance, and a suspension system tuned and optimized for rail cars to have a minimum reserve capacity of less than 1.5 to improve motion control and ride quality, increase resistance to suspension bottoming, and increase hunting threshold speed. Such a motion control truck system is able to meet recent, more stringent American Association of Railroads standards, such as M-976, for railcars having a 286,000 lb. gross rail load rating.
