Abstract
A truck apparatus for a railway car includes a pair of wheel sets each having a pair of wheels joined by an axle. A frame is provided for carrying one end of a railway car body and a system positions the frame in a pendulum fashion from each axle end in order to independently decouple, from each other, vertical, lateral and longitudinal forces applied to the frame by the wheel sets during operation of the railway car.
