          1: Don’t let the single
        
        
          turnout fool you. This
        
        
          warehouse has six doors,
        
        
          each a separate car
        
        
          “spot,” that essentially
        
        
          act like mini-industries.
        
        
          You don’t just waybill a
        
        
          car to the warehouse;
        
        
          you need to deliver it to
        
        
          a specific spot. Operated
        
        
          in this railroad-like
        
        
          manner, even simple
        
        
          track arrangements can
        
        
          take a half hour or more
        
        
          to switch.
