What looks like as small yard are actually six main lines representing four of the five Class 1 railroads operating in Memphis, Tennessee. UP 7895, on the UP Memphis Sub main, and UP 3946, on the NS Memphis District west main, are at Tower 17 in downtown Memphis waiting to go west. An empty Miller coal train, also looking to go west, sits on BNSF Thayer South Sub main 1 with the head end out of picture at CN Junction. So, from left-to-right, CSX Memphis Terminal Sub, NS Memphis District west main, UP Memphis Sub, NS Memphis District east main, BNSF Thayer South Sub main 2 and BNSF Thayer South Sub main 1.
