Abstract
A modular center filler and center plate may be constructed as a unit away from the car and adapted for connection to the center sill webs of a railway vehicle. The center filler has a thick bottom plate which extends beneath the center sill and has pairs of interconnected longitudinal and transverse sill reinforcing plates arranged in a double I-beam manner. The center plate has longitudinally extending attached skirts, and bevels are provided which allow the car to rock at the bevel lines. Forces transmitted through the center plate at the bevels are absorbed and distributed by the associated longitudinal plates and other bolster and center filler structural elements.
