This is Norfolk Southern’s Yuma yard looking east (top photo) with the Smith signal unit to the left. Bottom photo is looking west. This yard, 3 miles west of Frisco yard, is mostly used for storage now. It is .86 mile long with seven tracks. Thanks to the CSX Transportation Historical Society website for information on this yard.
