Above left is the plan for the corner at Salmon hole Bridge. The 18" radius circle drawn in the center of the sketch is the space reserved for the helix up to the second level for Kingfield if and when the time comes. For now, it will be rolling hills with the transition from Fall to Winter in the scenery.
Upper right is Porter Brook trestle along with Strong, and the radius for the track for the F&M branch that will lead under the layout to the hidden fiddle yard. The 5'-4" stretch of wall and notes on the sill are the double window in the wall that I had to take into account. That determined the height of the layout along that wall, and nothing critical is there in the scenery that might get damaged if I have to open or close the windows.
To the right is the diagram for Farmington. Note that the heavy lines for track are the standard gauge Maine Central rails, and the thinner lines are the narrow gauge SR&RL rails. As mentioned earlier, the MEC engine house will be oriented with the doors facing to the left, and there won't be a spur on the wye blocking the door into the room, sketched in on the right.
