  • Method of manufacturing a multiple axle railcar having a span bolster
    Patent number: 10766507
    Abstract: A method for making a railcar having a span bolster is disclosed. The method involves fabricating and joining the components of the span bolster in a manner such that a camber is built into span bolster. A camber is cut into longitudinal supports that span the length of the bolster. A jig is used to shape top and bottom plates prior to attaching the plates to the longitudinal supports, thus forming the bolster. Truck assemblies are attached to the bolster and a railcar body mounted to the combined unit.
