I started dismantling a good portion of my layout yesterday. I will be moving the 6 track yard, outer mainline and service track to the far wall and triple their length. I am eliminating my duckunder and will be installing a dutch door water scene to enter the room. I think this new 'perimeter' design will be more operator friendly. Three new scenes will be. Blast Furnace and Casting House, Steam Engine Facility and a water scene with tug and barge.
