摘要： A modern scenic passenger railcar system is disclosed. The railcar system incorporates design and safety features of modern freightcars and modern passenger scenic railway cars. The railcar system incorporates a center beam with a square cross section as well as specialized crash posts with its frame. This results in enhanced safety and crashworthiness. The railcar system also incorporates cross members for absorbing and distributing shock and mechanical stress on the railcar system during use, by withstanding torsion and shear forces on the frame. This results in improved mechanical integrity of the frame and the railcar system overall.

摘要： A covered hopper railroad freight car having a car body whose opposite longitudinal sides include generally flat, parallel, substantially vertical upper side wall portions free from outwardly protruding structural strength members. A top chord of each of the side walls of the car is defined by a pair of parallel bend lines extending longitudinally along the upper margin of each side wall, and a roof is welded to the top chords of the side walls.

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.

摘要： The ultralight two track train that does not derail, made up of one or more ultralight wagons and aerodynamic, oval or semi-oval transverse profiles, characterized in that the wagons carry vertical or inclined wheels or pulley wheels in their lower area and supported by the chassis of the wagons, which rest and roll on a pair of vertical or inclined rails, the channels of the pulley wheels are supported and held on the head of circular, semicircular or semi-oval section of the rails, the heads of the rails being trapped with the pulley wheels, adding pairs of wheels that use a common axis, the rails are coupled and fixed tongue and groove to the sleepers or to some monolithic structures or channels, the sleepers are fixed using the track system on concrete slab, using electrical supply means, propellant means and reducing means of the front, rear and lateral resistance of the wagons, adding wheels with permanent magnets or with electromagnets that are attached, or run close and attracted by the rails.

摘要： A covered hopper car including a plurality of hoppers adjacent one another along the length of the car, with a generally vertical stiffened bulkhead of sheet material between adjacent ones of the hoppers. The bulkhead may include a plurality of stiffeners of which each stiffener is a transversely oriented curved portion of the sheet material of the bulkhead itself, displaced from the vertical main plane of the bulkhead. A radius of curvature is great enough and all surfaces of the stiffener are steep enough that granular material will slide downward from the stiffener and all surfaces of the stiffener can easily be washed by a spray directed from a hatch opening in the roof of the covered hopper car.

摘要： A method of assembling a body of a rail vehicle includes steps of: creating a numerical model of at least one specific module; dimensioning in the numerical model, the position of fixing holes in the specific module, the dimensioning of each fixing hole being defined at least with respect to one edge of the specific module extending in a direction of greater length of the specific module and with respect to an axis transverse to the longer direction; supplying the specific module; drilling the fixing holes in the specific module by a drilling device at the position listed in the numerical model; and assembling the body, the assembly including attaching the specific module to at least one adjacent module utilizing a fixing unit inserted into the fixing holes drilled in the specific module.
