I have finally completed the as-built drawing of the layout, though it is still waiting on working up the turntable/roundhouse. The rest is pretty darned accurate - certainly good enough to begin documenting the wiring and placing the scenery. The whole thing is 6x10 ft. I tried to pack a lot of things into this, including to long main lines (one uninterrupted -- the gray box at the top is a mountain tunnel), a yard lead and moderately complex yard (if a bit short) with a runaround, and two entrances to the turntable to get engines out onto the line quickly. The triangle at the lower right is the control panel. Now to finish the wiring of all the turnout track. Do I really need to wire up all the frogs to the switch machines? It will be a major PITA, but I suppose it will improve performance... Is it worth it?
