This would prevent regular gold powered rails from becoming obsolete. This way, the player would have to occasionally reapply wax to the rails to keep them from oxidizing, providing an incentive to upgrade to gold rails. The justification, "lore" wise, is that the wear and tear of use rubs the copper off. There's a lot of friction between the wheels and the rails, so it makes perfect sense that the wax coating would eventually deteriorate.
In order to alert the player, the un-waxing particle effect/sound would play when this happens.
