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.

Claim (Index 2):
The method of  claim 1 , wherein fabricating a span bolster having a camber comprises:\n cutting a longitudinal stringer in an arc shape; forcing a top plate against a first jig to elastically deform the top plate, wherein a contour of the first jig is shaped to substantially match a profile of a top surface of the longitudinal stringer; attaching the top plate to the top surface of the longitudinal stringer, wherein the top plate is retained in the first jig under force until attached to the longitudinal stringer; forcing a bottom plate against a second jig to elastically deform the bottom plate, wherein a contour of the second jig is shaped to substantially match a profile of a bottom surface of the longitudinal stringer; and attaching the bottom plate to the bottom surface of the longitudinal stringer, wherein the bottom plate is retained in the second jig under force until attached to the longitudinal stringer.
