Bob downloaded the PDF article on building concrete mountains and many bags of plastic cement later he has built a fabulous system of mountains and tunnels for his outdoor layout. Bob sent me several pictures of what he was able to build on his layout so far.
Bob has a number of tunnels running through his mountains where his tracks loop around in front of his observation and control booth.
Here you can see the approach to the turns. Note the drop off in the foreground.
Here is a great view of Bob’s layout. Note the bridge in the right background which goes over the future water feature. The layout is still under construction.
Bob really did a great job incorporating the cement work into his layout.
Here you can see how Bob ran a drain through his retaining wall.
