Further for a little explanation of the meaning of: "following your instructions relative to necessity of re-driving the spike to its proper position after the tie plate has property imbedded itself in the tie"
The RGS was using tie plates which had a number of very sharp 1/4" high ridges on the bottom side which were built to cut into the tie and provide holding strength to the shoulder lip that held the rail to prevent rail spread. When first laid on a tie, the plate would sit 1/4" high off the tie until the numerous engines movements would force the plate flat onto the tie. Then the spike would be 1/4" high and need to be re-driven as the manufacturer suggested. I see that as a costly defect of the tie plate design and not the spike maker’s fault. All this in addition to the need of a special tool to pull the spike from the side, where there is little support for the leveraging of the pulling lever.
Few know that the present day spike's proper position is not touching the rail but 1/32" above the contact with the rail. Rail anchors are used to prevent rail movement laterally. The modern tie plates only have a very minimum ridging on the bottom so the plate fits to but will not break the wood fiber. The old RGS style cut across the fiber of the wood and caused quicker deterioration with water entry and rot where it cut into the tie.
