Hanna and Hanna coal marshaling yard. We model 3 mines, and the Hanna coal job entails being the coal agent (going around the layout as far as Cheyenne to inventory the empty hoppers to be replaced with loads), making up the train with the required number of loaded hoppers, delivering them, either setting the correct number to replace the MT's on spots or leaving them with a YM to do this. Finally, the operator drags the empties back to the mines or Hanna yard. So the job is a coal agent, YM (Hanna), and road crew--fun! The mines are behind the view block to the far left connected to the yard.
