A chain of semi-trailer vehicles is intended to be articulated to a main vehicle. Each semi-trailer vehicle includes a body and a single bogie supporting the body, known as a trailer bogie. The bodies of the semi-trailer vehicles are successively articulated to one another from a first semi-trailer vehicle of the chain by a separate inter-body joint. Each inter-body joint is carried by one end of each semi-trailer vehicle connected to a following vehicle. Each inter-body joint is articulated along a vertical pivot axis. Each trailer bogie of a body carries an inter-body joint arranged longitudinally with respect to the body so that the bogie axis and the interconnection axis are offset.

A rail vehicle for transporting people, which is in the form of an articulated train-type multiple unit, includes at least two car bodies. Adjoining car bodies are supported on a common central running gear and end car bodies are additionally supported on end running gears. All of the running gears have a distance between the centers of the bogies of two adjoining running gears of from 18 to 21 m, and the end car bodies have a length of from 24 to 27 m.

A railroad car truck for a railroad freight car, such as an autorack car, has a bolster mounted cross-wise between two sideframes. The bolster ends are mounted on respective spring groups carried by the sideframes. The bolster can translate laterally relative to the sideframes. The side frames are mounted to swing laterally relative to the wheel sets, and hence relative to the rails. Resistance to lateral deflection is provided by the resistance of the sideframes to the pendulum swinging motion, and by shear in the spring groups. The truck has a doubled damper arrangement of dampers in a four-cornered layout at each end of the bolster, giving a flexing resistance to yaw between the sideframes and the bolster ends. The doubled damper arrangement works against large wear plates mounted on the sideframe columns. The large wear plates are mounted normal to the dampers and square to the sideframes.

Disclosed is a fairing (3) for an articulated railway vehicle bogie, this fairing including: a bottom wall (30) and side walls (31) able to surround at least a lower part of a bogie, and first and second anchoring zones (51, 52) each able to be fastened to one end, respectively, of a first body and a second body of a railway vehicle that are articulated relative to one another, in a configuration where these first and second bodies rest at least partially on the bogie. The fairing (3) includes a flexible connector (4) that mechanically links the first anchoring zone (51) and the second anchoring zone (52) and that authorizes a movement of these first and second anchoring zones relative to one another.

Disclosed are various embodiments for an automatic locking system for railgear. In an embodiment, the automatic locking system for railgear is an automatic mechanical locking system that can be incorporated into a front guide railgear assembly for use with conventional roadway vehicles. The automatic locking system can secure the railgear in a fixed orientation, either deployed for rail travel using the guide wheels of the railgear on rail tracks or stowed for highway travel such that the vehicle can operate using the conventional tires on a road, highway, and the like.

The railway vehicle (10) includes a plurality of cars (12, 20) articulated to one another, the plurality of cars including: a single first key car (12), having a first architecture, a plurality of second cars (20), having similar second architectures different from the first architecture. The first key car (12) has no dining area.

The railway vehicle comprises at least one end car, each arranged at a respective end of the railway vehicle, and, for each end car, a first car adjacent to this end car, and at least one second car, one of which is adjacent to the first car. Each second car comprises a second structural body. Each first car comprises a first structural body substantially identical to the second structural body of each second car, and a structural extension part attached on the first structural body and intended to be connected to the adjacent end car.

A method for making a railcar having a span bolster is disclosed. The method involves fabricating and joining the components of the span bolster in a manner such that a camber is built into span bolster. A camber is cut into longitudinal supports that span the length of the bolster. A jig is used to shape top and bottom plates prior to attaching the plates to the longitudinal supports, thus forming the bolster. Truck assemblies are attached to the bolster and a railcar body mounted to the combined unit.
