NS U52 slowly rolls east on the ex-Interstate Railroad's main line at the east end of Andover Yard. The crew has 23 commercial loads in tow that it loaded at Wentz during the morning. The metal building in the left background is associated with weigh-in-motion scales. Once the rear clears the switch to the track to the left, U52 will shove the loads over the scales before placing them in the yard.
