A rotating part that includes at least one generator unit having at least one coil, at least one permanent magnet and two pole shoes having pole surfaces facing radially outward is provided, The non-rotating part has an arc-shaped saddle adaptor of ferromagnetic material arranged with a radial distance to the pole surfaces. The saddle adaptor is configured to close a magnetic circuit passing via the pole shoes through the coil in a rotational position where the saddle adaptor overlaps with the pole shoes of the generator unit.

A railcar truck and adapter pad system for placement between a roller bearing and side frame pedestal roof of a three-piece railcar truck. Many different features of the pad and/or the adapter-pad interface are configured to improve stiffness characteristics to satisfy both curving and high speed performance of the railcar truck.

A truck assembly for a rail vehicle includes at least one side frame including at least one lightener hole. At least one strain gage is disposed within the lightener hole(s). The strain gage(s) is configured to detect forces exerted into or onto the truck assembly. A method of detecting forces exerted into or onto a truck assembly of a rail vehicle includes disposing at least one strain gage within at least one lightener hole of at least one side frame of a truck assembly of the rail vehicle, and detecting the forces by the strain gage(s).

A side bearing assembly for a truck assembly of a rail vehicle includes a base, a cap moveably coupled to the base, and one or more elastomer springs disposed between the base and the cap. The one or more elastomer springs include a foam having air pockets that are configured be compressed.

A vehicle truck includes a first side frame, a second side frame, a bolster, a first yaw separator connected to the first side frame, and a second yaw separator connected to the second side frame. Each yaw separator includes two steering arms and an arm connector assembly. The yaw separators are configured to alter yaw movement of the truck that leads to truck hunting.

A truck assembly of a rail vehicle includes a side frame including a spring seat below an opening. The spring seat includes a locating pocket. An end guide system is coupled to the side frame. The end guide system includes a central base configured to be received and retained by the locating pocket. At least one end guide extends outwardly and upwardly from the central base.
