ABSTRACT:
A railway vehicle having twelve wheel and axle assemblies grouped into six 2-axle truck assemblies. Three truck assemblies are mounted on each of two span bolsters which in turn are mounted on opposite ends of a railway vehicle. All of the truck assemblies are rotatably mounted to the span bolster and the span bolster is rotatably mounted to the rail vehicle. The center assembly can be rotatably mounted about an axis common with the axis of the center plate of the span bolster. In some embodiments the spring assembly on the center truck assembly of each span bolster is lighter than the spring assemblies on the other truck assemblies mounted to the same bolster. In some embodiments the center truck assembly can move laterally more than the other truck assemblies on the span bolster.
