I have started to build some dioramas around the layout.  One corner is set up as the train depot. The train leaving the depot  passes a siding that stores the Christmas train, as it moves toward the farm area.  The command center is located along the wall in this area. 

The train enters a long stretch across the back of the room after it leaves the farm area.  There is a passing siding on this wall that is used to store either the Chessie diesel or my Pennsylvania Steamer.  One can here that familiar diesel horn as the Chessie enters the corner set up as a city.  There is a banjo type crossing signal that animates that corner before the train moves toward the cabin and oil field.  There is a working barrel pump with field lights just before the sand tower that was used for traction on the rails.  Finally our journey nears its end as we cross the "fire stove pipe" by going over the compression style trestle bridge. Another small passing siding after the bridge is available for slow trains or storing a train.  The journey is completed as we pull back into the depot.
