2 The complete layout - deliberately left unlcuttered to give an illusion of space. And because I am lazy.
3 While only 4' long, this is equivalent to 24' x 5' in OO as this end view clearly shows.
4 Much the same from the other end.
5 Behind the scenes, with enough room for 3.5 full-length trains. Controls are built-in, road on the left and rail on the right.
6 Oops. Look away for a minute, and see what happens!
7 Road controllers on the left, rail and crossing on the right. Servos (blue) for the gates in the center. What fool put a frame timber right next to the crossing?
