Preparing to load a unit train at Kopper Glo off the Clearfork Branch, NS spots mtys under the 200 foot tall coal loadout silo which holds about 8,000 tons of cleaned and prepped coal. They load in halves, with power for the second cut sitting on the house track below and to the right. The mtys for the second half are above and just to the top out of the pic, stored on a siding. If one looks closely at the shadow of the loadout silo splayed out across the tracks, you can see the small protuberance which is the shadow of the photographer from atop the silo.
