摘要:
A rail car truck bolster wear plate surface connects to a wear plate using two fasteners of different length. The first fastener passes through an upper opening and an upper channel into a first recess where it can be tightened against a first engaging surface. The second fastener is longer than the first fastener and passes through a lower opening and lower channel into a second recess adjacent to the first recess. The surfaces of the first and second recesses form a series of ribs in the upper end surface between the wear plate surface and the longitudinal centerline of the bolster.
