What should be done to a hole when cut spikes are withdrawn from a tie?

When cut spikes are withdrawn from a tie, it is important to plug the holes that are left behind. Plugging the holes serves several purposes. First, it prevents water and debris from entering the tie, which can lead to deterioration of the wood or damage to the underlying structure over time. Second, it helps maintain the integrity of the tie by reducing the likelihood of further splitting or weakening of the wood around the hole. Lastly, plugging the holes aids in maintaining a smooth surface for future maintenance and ensures that the area is safe for both operation and maintenance activities.

Other options do not address the long-term integrity of the rail tie. Leaving the holes open would leave the wood exposed to environmental factors, drilling could damage the tie further or create unnecessary wear, and reinforcing may not be relevant in this context as the primary concern is sealing the holes to prevent deterioration.
