A railway car truck interface assembly comprising:
- a railway car truck bolster, the bolster including a center bowl of circular shape with a raised wall and a centrally located opening,
- a horizontal wear liner received in the bolster center bowl,
- a center plate having an upper section comprised of four sides and a lower section, the lower section having an outer circular edge extending downwardly from the upper section, the center plate including a centrally located opening,
- the lower section of the center plate received in the bolster center bowl, with a pin extending into the centrally located opening in the bolster center bowl and into the centrally located opening in the center plate,
- an annular edge wear liner between the center bowl raised wall and the outer circular edge of the lower section of the center plate, the edge wear liner including a metallic spring material;
- and
- an undulating wall of the edge wear liner intermediate the center bowl raised wall and the outer circular edge of the lower section of the center plate;
- wherein the edge wear liner has a split-ring configuration that allows the edge wear liner to be elastically compressed when the center plate is placed in the bolster center bowl.
