摘要:
Typically, a tie plate assembly for supporting a rail on a tie includes a tie plate and a spike that is driven through the plate into the tie to secure the tie plate to the point. A sleeve is provided on the plate that is inserted into a tie to prevent the deflection of the spike with respect to the ties wheels of a train pass over the tie.
