Abstract
A railway car body structural arrangement has a bolster fabricated from plates and formed on the upper surface of a bottom closure member of the body of a railway car and rigidly affixed to a bolster post at each side of the car. The lower portions of the bolster posts are affixed to the bolster assembly adjacent to the upper surface of the bottom closure member to enable use of a continuous side sill member on the car. Bearing surfaces which limit the transverse angular movement or roll of the car body with respect to a truck are attached to and project downward from a lower surface of the frame of the truck which is supportingly and pivotally engaged with the center sill substantially directly beneath the bolster.
