As info, in Durango during the 70's, the 1-2 trains that operated didn't use much sand. the DRGW practice at the time was to spread green sand on the floor of the dry room to dry. They would then shovel through the screen separating the dry room from the storage room, where the sand was then shoveled into the lower hopper for lifting. This practice usually would get them through the summer. After the arrival of the D&S, more and more locomotives were put into service and sand was always at a premium. We started drying sand (using the stove) to screen and stockpile about mid winter. As spring and summer came around, any extra time that we had in the shop, the laborers and engine watchman spent in the sand house drying and screening so as to keep up through the summer. If the roundhouse foreman saw anyone standing around with nothing to do....they ended up in the sand house doing something.
