ABSTRACT:
An articulated truck center connection of known construction joins extensions extending in opposite directions from the transverse center of adjacent car end portions to the center plate of a truck supporting the adjacent ends of the cars. A pair of side bearings are mounted on the truck bolster on opposite sides of the articulated center connection. Each side bearing includes a rectangular channel or tube mounted on the truck and a first bearing surface which receives a first extension from one adjacent car end. The first extension is free to slide horizontally on the first bearing. The channel or tube extends above the first bearing surface and a second extension from the other adjacent car includes a depending bearing member which rests upon and is supported by the first bearing member. A pivot allows the second car end to rotate vertically about the center connection as the cars transverse vertical inclines. The depending member is free to slide upon the upper surface of the first bearing member as the second car end rotates horizontally relative to the truck.
