The beginning of the Maysville climb, which goes to two areas. One would be over to Cumbres and the other would be up to the second level via the switchbacks. Both should be a lot of fun to operate.
The small shelf at the front of the divider wall you see is the turn around point for the lower loop of the layout (coming from the Salida yards). Yes...it is through two holes in the wall, as you see in this picture. The upper hole is for the re-directed loop that goes over the small shelf over Salida as well. (Can you believe I have such a great understanding wife that she let me make 4 holes in a wall. Granted I have to fix them too, but I'll cross that bridge when I get there).
