Well, before you asked your question on the 8th, Tahawus84 made a flat-out statement: "from the photographer: Well snc is not hauling coal they are storing it on the sidings at Thurman, White sand, Corinth, river side, Kings, and at Saratoga station temporarily for CP." Pretty specific and apparently no doubt. After you read it from a couple other sources, you then twice told us what Tahawus84 already had said. My point was there didn't seem to be any question about the accuracy of the first post and while you
may have wanted more confirmation it seemed plain to me. I'm not losing any sleep about it.
As for your question about making money, such arrangements are private deals negotiated between the railroad(s) and the party needing storage, but USUALLY they involve both a transportation charge for the move itself, plus a per-day or per-week fee for as long as the cars stay on line. It's really a good deal for the railroad, as they can take some unused siding or branch, and get money from an asset that was essentially useless. It's even a good deal for railfans, giving an opportunity to see cars on some track that would otherwise be weed-covered. Not to mention the added photo ops for the movement of the storage cars in or out.
