摘要： A center beam car has a main deck structure extending laterally from a main center sill, a laterally extending top truss structure, and a central vertically oriented central beam structure. The center beam so formed defines bunks in which to carry cargo. The upper region of the web-work structure includes a top chord mounted to run between two end bulkheads. The deck has a central portion and end portions. The end portions of the deck are carried at a greater height than the center portion, the difference in height corresponding to the height of a bundle of lumber. The car has a center sill having a depth corresponding to the depth of the step in the deck. The end portion of the center sill has an internal plate defining a draft gear pocket upper wall. The medial portion of the center sill is narrower than the end portion, and of deep section, such that it has a high aspect ratio. Web separators are mounted in the medial portion of the center sill by a method that includes making part of the weld from outside the center sill through welding apertures. As the end deck is carried at a high level, the bolster is abnormally deep.
摘要翻译： 中心梁车具有从主中心梁横向延伸的主甲板结构，横向延伸的顶部桁架结构和中心垂直定向的中心梁结构。 这样形成的中心梁定义了运载货物的行李箱。 腹板工作结构的上部区域包括安装成在两个端部隔板之间延伸的顶部翼弦。 甲板具有中心部分和端部。 甲板的端部承载在比中心部分更大的高度上，高度差对应于一束木材的高度。 汽车具有对应于甲板中台阶深度的深度的中心门槛。 中心梁的端部具有限定出牵引齿轮槽上壁的内板。 中间梁的中间部分比端部部分和深部分窄，使得其具有高纵横比。 Web分离器通过一种方法安装在中心梁的中间部分中，该方法包括通过焊接孔从中心梁外部制造焊接的一部分。 由于末端甲板是高水平运载的，所以支架异常深。

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 co-operate 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： An auto rack rail road freight car is provided for carrying low density, relatively high value, relatively fragile lading. The car has a relatively soft suspension and an empty vertical bounce natural frequency of less than 2.0 Hz. The car also has additional ballast to increase the dead sprung weight of the car relative to the weight of the lading. In the embodiments in which multi-unit articulated freight cars are employed, such as for auto rack rail cars, the ballast is located preferentially toward the coupler end trucks. The trucks for the railcar have an increased wheel base and damping located to provide a greater moment arm and bearing face to encourage a higher threshold for rail car hunting.

摘要： A center beam car has a main deck structure extending laterally from a main center sill, and a central vertically oriented central beam structure. The center beam so formed defines bunks upon in which to carry cargo. The upper region of the web-work structure includes a top chord mounted to run between two end bulkheads. The cargo can be secured to the deck with straps or webs. When the car is empty the straps or webs can be stored within boxes that are accessible at deck level by a person of average height. The storage boxes can be along the center line of the car, between the posts of the center beam, or they can be located adjacent to the side sills. Further, the boxes can be movable to a raised position, or to a lowered, stored position. A reeling mechanism is provided to facilitate winding of the straps or webs for storage.

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： An articulated railcar has several well car units for carrying shipping containers, highways trailers, or a combination of the two. The well car units permit the nose of a highway trailer to overhang the articulated connection between two adjacent cars. A brake valve is located in a relief formed in the main bolster of one of the articulated units, out of the way of the overhanging trailer. Each well car unit has a side beam having a roll formed top chord reinforced by a top chord plate, a downwardly extending web, and a lower sill formed of a thick angle. The service, or auxiliary, and emergency brake reservoirs are mounted in a saddle bag configuration to the outside face of the webs of the opposite side beams of the articulated unit, tucked underneath the reinforced roll formed top chord.

摘要： A railcar unit has a pair of opposed side sills that are joined by structure that performs the function of a web in a deep beam or bracing in a truss. The joining structure is able to transmit loads that are applied transversely to the longitudinal direction of the car from one sill to the other, and is also able to transmit a bending moment couple, in the form of opposite longitudinal tensile and compressive forces, also transmitted to the side sills. The locations at which the transverse forces are imposed on, or by, the intermediate structure have longitudinal slip. When the railcar unit is placed in longitudinal tension under draft loads, the longitudinal slip allows the floor structure not to be subject to the longitudinal draft loads. In the embodiment described the joining structure serves the additional function of acting as a floor panel for vertical loads carried within the well car unit.

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 rail road car truck has a bolster having the form of a hollow beam that has a deep central portion and shallow ends. The bolster has a top flange, a bottom flange and internal and external webs extending between, intersecting and merging with the top and bottom flanges. A center plate bowl is located in the middle of the top flange, and brake rod passages are defined transversely through the bolster. In some embodiments, transverse ribs run underneath the center plate bowl. The ribs may be curved. The ribs may be flush with the brake rod openings in the various webs. There may be upwardly standing ribs running transversely across the bottom flange. Those lower ribs may terminate upwardly flush with the brake rod openings. Alternatively, the bottom portion of the bolster may by cast with a greater thickness, up to the bottom of the break rod openings. In other embodiments, the bolster may have partial or fully tubular brake rod opening liners or tubes that extend across the bolster beneath the center plate.
