摘要： A rail spike for holding a tie plate on a tie, embodied in accordance with the invention so that tie cutting is prevented, spike removal for track maintenance is facilitated, and a free rail load wave is allowed. This preferably is attained by providing the spike with left and right side tapered shoulders and a tapered rear surface, such that a unique wedging and swaging action occurs in the tie plate hole during a final driving of the spike, limiting the depth of penetration of the spike into the tie and securely maintaining the gauge of the tie plate on the tie.
