ABSTRACT:
A railway car center plate assembly comprising a truck bolster having a bowl-shaped truck center plate and a body bolster having secured to its underside a body center plate. The body center plate has a flat surface from which extend downwardly two substantially perpendicular, concentric, cylindrical flanges encircling a bore, the diameter of the outermost flange being such that its outer vertical surface is encompassed by the inner vertical surface of the flange on the truck center plate. Positioned between the body center plate and the truck center plate is an annular, synthetic elastomeric bearing pad which is located within and substantially fills the annular space between the flanges of the body center plate and under load contacts the vertical surfaces of the flanges of the body center plate.
