Re: Chalk Marks Question

From my research the wax crayons were favored by Federal inspectors for their water resistance. For railroaders chalk was easier to wipe off so that out of date instructions were eliminated. If weather was a problem marks on boxcars would be made under the door track. Truck frames also were marked as an alternative.
