I think there's another issue involved, more than convenience in loading. For a while last year (not sure if it's still going on) the scrap ties were being rail-hauled to a plant in PA that was burning them for energy recovery.
the local logistics was interesting. Around Delanson, the ties were hauled back into Delanson in conventional low sided gondolas, unloaded and stockpiled on the ground, and then eventually reloaded into what appeared to be former coal-train high sided gons for the trip into PA.
At a couple of locations where ties were lying in between small trees, the operator pulled the tree out by the roots and added it to the pile of ties on the gon. Not sure if the tree got shipped to PA or not.
