ABSTRACT:
A railway truck has a frame, and two wheel-sets operatively connected to the frame. Each wheel-set includes a corresponding axle, and two wheels disposed on the axle. A first steering lever is pivotally connected to the first end portion of the first axle about a first pivot axis and to the frame about a second pivot axis. A second steering lever is pivotally connected to the second end portion of the first axle about a third pivot axis and to the frame about a fourth pivot axis. A first line passing through the first and second pivot axes crosses a second line passing through the third and fourth pivot axes at less than a predetermined distance from a vertical centerline of the truck when the first and second axles are parallel. A railcar including the truck is also provided.
