The last SOO unit is slowly coming back home to Bensenville Yard as I freak out behind the camera. I had planned this visit to Bensenville just to see this unit, but it left to go the Saint Paul literally two days before I left. I would have canceled the trip, but I already paid for my hotel reservation so I went anyways. Then the unit just appeared out of nowhere on the return train to Bensenville. I followed it back to the yard and watched it switch for half an hour. This is one of my greatest catches of all time.
