Burlington Northern caboose No. 10037 trails eastbound empties at Sully Springs, North Dakota, on August 9, 1991. The locomotives of the short train have just passed the power of a coal load in the siding. The head end brakeman of the westbound is on the ground for a roll-by, and answering a call to nature as any good crew member would do, instead of using the head in the nose of the locomotive.
