A rail road freight car may have a body for carrying lading. The body may be a gondola car body. The car body may include a decking or floor structure, and may include longitudinally extending side beams bordering the floor structure. The connection of the side beams to the floor structure may be may without the use of a dedicated side sill. The car body structure may include cross-bearers and side beam stiffeners that are joined together by structural knees. The car body may also include clean out ports to facilitate cleaning of the lading receptacle.

The embodiment of the invention discloses a green logistics service system, which comprises a material transfer storehouse, a material dispatching center, a material distribution center and a railway transportation center, and is characterized in that the material transfer storehouse is used for storing transfer materials transported from the material distribution center; the material dispatching center determines a material transfer storehouse and dispatches an electric vehicle; the material distribution center sends the electric vehicle to a railway freight yard to load the materials and transport the materials to the material transfer storehouse; the railway transportation center sets transfer material information for the materials to be transferred and transmits the transfer material information to the material dispatching center, by using a transportation mode of combining a city distribution electric logistic vehicle and a railway electric locomotive, and the materials to be transferred are transported and carried by relaying on a railway freight electric locomotive; and positioning information of the running railway electric locomotive is acquired, and the acquired positioning information is sent to the material distribution center. By applying the green logistics service system, truck exhaust gas emission pollutions are solved from the source, and an innovative new energy circulation industry which is capable of saving energy, reducing emission, relieving the traffic and reducing fog and haze, safe and efficient is constructed, thereby building a modern smart city big traffic livelihood green logistics sustainable development system.

A rail road freight car truck, which may be a Barber S2HD truck or other kind of truck, has a truck bolster and a pair of side frames, the truck bolster being mounted transversely relative to the side frames. The sideframes are mounted on a pair of wheelsets. The bolster may be resiliently sprung and may have friction dampers. Either the friction dampers or the sideframe column wear plates may have a non-metallic wear plate, or wear surface, which may be replaceable, and which may tend to exhibit non-stick slip, or reduced stick slip behaviour in use. Bearing adapters may be mounted on the bearings of the wheelsets, and resilient pad members may be mounted on the bearing adapters. The pedestal seats may sit over the resilient pads. There may be a discontinuity in the vertical load path between the pedestal roof and the bearing. The discontinuity in the vertical load path may tend to shed a portion of the vertical load to either side of the top rollers of the bearing races to a greater extent than if the vertical load path discontinuity were not present.

A drop-center rail road freight car may have a gondola body for carrying lading, which may have end sections and a deep central section therebetween. The body may include a decking or floor structure, and longitudinally extending side beams bordering the floor structure. The car may have U-shaped bending-moment transmitting cross-bearers. The cross-bearers and side beam stiffeners may have inner and outer flange continuity such as to transmit a bending moment. The car may have stub sills. The stub sills may each have an inboard gooseneck that extends downward and inboard. The gooseneck may have a longitudinally extending portion that connects to the endmost cross-bearer of the central portion of the car. The main shear plate may lap the side sills, and may be bent downwardly to mate with the end margins of the side sheet lower portion to form a converging box-like truncated pyramidal structure.

The invention relates to an automatic limit detection device for a rail freight train to realize automatic limit measurement of the freight train. The device comprises a T-shaped supporting frame, animage data acquisition module, a data processing module and a rail coordinate datum target. The T-shaped supporting frame comprises a hook connector, a telescopic vertical rod and a transverse rod, wherein the hook connector is positioned at the bottom and matched with a connection hook between freight train carriages, one end of the telescopic vertical rod is connected with the hook connector, and the other end of the telescopic vertical rod is in rotational connection with the transverse rod through a rotatable connector. The image data acquisition module is arranged on the transverse rod and used for acquiring forward and downward surface images of the freight train. The data processing module comprises a data processing terminal which controls the image data acquisition module to shootsynchronously through a hard trigger synchronizer. The rail coordinate datum target is used for establishing a rail plane-coordinate system to fit a rail plane. Compared with the prior art, the automatic limit detection device has advantages of movability, one-man operation, high measurement accuracy and the like.

The invention provides an auxiliary device for railway freight, and relates to the field of railway freight. The auxiliary device comprises a rack, an overturning control mechanism, an overturning boxassembly, an intermittent rotation control mechanism, a power transmission mechanism and a transfer box assembly. The auxiliary device has the beneficial effects that cargoes are evenly distributed into each transfer box, the cargoes are equivalently distributed, it is guaranteed that the cargoes in each transfer box are equal, the operation that the cargoes are manually carried into the transferboxes one by one, and it cannot be conveniently guaranteed that the cargoes in each transfer box are equal through manual carrying is omitted, and the working efficiency is improved. The overturningcontrol mechanism is arranged at the upper end of the rack, the overturning box assembly is rotationally connected to the upper end of the rack, the overturning control mechanism and the overturning box assembly are in engaged transmission connection, the intermittent rotation control mechanism is fixedly connected to the middle of the rack, the intermittent rotation control mechanism and the overturning box assembly are in transmission connection through a belt, and the power transmission mechanism is fixedly connected to the intermittent rotation control mechanism.
