摘要： An auto rack rail road car has a main deck and upper deck. It is provided with a door for controlling access thereto. The door is a radial arm door, and has a ladder mounted thereon by which personnel can ascend the second deck when the door is open. A second ladder is mounted to the first deck so that when the door is open the second ladder is positioned to cooperate with the first ladder. The arcuate path of the door is free from overhanging obstructions. The door also has internal and external weld-free stiffeners member for enhancing the rigidity thereof. A roller mounted to the door permits the door to be moved between open and closed positions. The door may further include a lock. A guide member protruding from the door co-operates with a groove in the main deck which slidingly guides the door as it moves between open and closed positions to control access to the car.

摘要： A coil car has a pair of deep side sills and a trough structure mounted to, and suspended between, the deep side sills for carrying coils. The side sills extend between the rail car trucks and act as a pair of deep side beams for carrying vertical loads. The deep side sills are arranged to extend above and below the center sill of the coil car to give vertical stiffness to the coil car. The top chord members of the side sills are outwardly splayed relative to the bottom chord members of the side sills. Cross-bearers extend outwardly and away from the center sill to attach to the side sills. The trough structure has three parallel, longitudinally extending troughsnulla central trough lying between two laterally outboard outer troughs. Each trough is shaped to cradle steel coils, or other similar loads, between its inwardly and downwardly sloping shoulder plates. The shoulder plates are lined with cushioning to buffer coils during loading or travel. The outboard troughs are mounted above longitudinally extending stringers and are carried at a greater height relative to top of rail than the central trough. The car has coil stops to discourage longitudinal shifting of loaded coils. The coil stops have rollers to facilitate repositioning during loading, and a mid-span step and hand grabs to facilitate climbing over the coil stop by personnel walking along the trough structure.

摘要： A coil car has a pair of deep center sill that is shallow over the trucks, and deeper at a mid span loaction between the trucks. The deep center sill supports a trough structure for carrying generally cylindrical loads, such as coils of steel. Cross-bearers extend outwardly and away from the center sill to attach to side sills. The trough structure has three parallel, longitudinally extending troughsnulla central trough lying between two laterally outboard outer troughs. Each trough is shaped to cradle steel coils, or other similar loads, between its inwardly and downwardly sloping shoulder plates. The shoulder plates are lined with cushioning to buffer coils during loading or travel. The outboard troughs are mounted above longitudinally extending stringers and are carried at a greater height relative to top of rail than the central trough. The car has coil stops to discourage longitudinal shifting of loaded coils. The coil stops have rollers to facilitate repositioning during loading, and a mid-span step and hand grabs to facilitate climbing over the coil stop by personnel walking along the trough structure.

Each trough is shaped to cradle steel coils, or other similar loads, between its inwardly and downwardly sloping shoulder plates. The shoulder plates are lined with cushioning to buffer coils during loading or travel. The troughs are lined to permit warm coils to be carried.

摘要： A railroad tank car may have external fittings, such as brake fittings. A low mount brake fitting is located in a recess formed in the end sill of the car or in the side sill of the car between the main bolster and the end sill. Where an end sill installation is used, the end sill may be asymmetric, with the recess being formed to one side of the center sill. Alternatively, the end sill may be offset longitudinally away from the striker, and a spacer inserted.

摘要： A railroad hopper car has a hopper carried between two trucks. The hopper has convergent end and side slope sheets that feed a flat bottom discharge. It has a rectangular frame at least half as wide as the car, and at least half as great as the truck center distance. The car capacity is over 5000 cu. ft. The bottom discharge is lower than the center sill. There are ring frames having a bottom reinforcement that passes clear under the center sill. The car has flat bottom discharge gates having multiple arrays of louvers. The side sheets extend downwardly beyond the side sills, so that the side slope sheets terminate at a transition below the side sills. The louvers have curved edges. The louvers move together. The gate may include two opposed sliding doors separated by a beam that runs under the center sill.

摘要： A damper wedge for a railroad car truck includes a friction member that rides on the wear plate of the side frame column of the railroad car truck and a non-metallic wear surface; and a spring seat that, in use, engages a spring of the railroad car truck. The inclined damper wedge surface has a primary angle alpha, and a secondary angle beta. The spring seat has an axial centerline. The inclined damper wedge surface has a curvature. The curvature has a working point. The damper wedge has a datum plane that is normal to the non-metallic wear surface and that contains the axial centerline. The axial centerline meets the inclined damper wedge surface at an intersection point that is the center of a contact patch. The working point is located in a central region of the contact patch, or working surface patch, downslope of the intersection point.

摘要： A railroad freight car has an underframe that includes a center sill and lateral cross-members such as bolsters, cross-bearers and cross-ties. Side sills run along the edges of the car. A floor sheet is welded to the center sill and side sills and above the cross-members. Floor stringers are welded to the top side of the floor sheet. A surface covering is mounted on top of the stringers. Thermal insulation may be installed between the surface covering and the floor sheets.
