A rail vehicle having at least a first carriage and a second carriage intercoupled via a carriage coupling device that has a variable resistance to twisting of the at least first carriage relative to the second carriage, wherein a first resistance torque gradient of the carriage coupling device at a first angular position of the at least first carriage relative to the second carriage in a direction of rotation is greater in magnitude than a second resistance torque gradient of the carriage coupling device at a second angular position of the at least first carriage relative to the second carriage in the same direction of rotation, where the first angular position is associated with a lesser twisting of the at least first carriage relative to the second carriage than the second angular position, such that an improved driving behavior of the rail vehicle is achieved, particular when entering track curves.

This articulation device for an articulated vehicle comprises a first shackle (14), a second shackle (16), and an articulation joint (18) comprising a first articulation member (20) comprising a single first section (52) and a second articulation member (22) comprising a single second section (60). The first section (52) and the second section (60) are rotatable relative to each other; the first shackle (14) is connected to the first articulation member (20) and the second shackle (16) is connected to the second articulation member (22). The second articulation member (22) comprises a single connecting member (66) through which the second section (60) is connected to the second shackle (16), the connecting member (66) being adapted to adjust the position of the second section (60) relative to the second shackle (16) along a longitudinal axis (X2-X2) and along a transverse axis (Y2-Y2).

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 symmetrical multi-unit railroad freight car, such as a 3-pack railroad intermodal well car, has body units that are connected symmetrically. The body units have a symmetrical arrangement of end trucks and shared trucks. The end trucks are 70 Ton Trucks. The shared trucks are 125 Ton trucks. The trucks have passive steering using geometric rocker stiffnesses. The rockers in the end trucks have a smaller radius of curvature than the rockers in the shared trucks. The spring groups in the shared trucks are stiffer than the spring groups in the end trucks. The spring groups in the end trucks have a different proportion of damping when empty, a shorter live load range of travel, and greater reserve travel than the shared trucks. The end trucks and the shared trucks have four-cornered damper groups that have the same sized damper wedges. The damper wedges have non-metallic wear pads.
