Clem, I appreciate your comment about O-96. I was wondering it it was possible, well it took some time and changing #8 cross-overs for #6, but it works. Nice!! O-96 minimum for both inner and outer mainlines. Three of the curves were already O-96, and it took some work to reconfigure to adjust the final three. People space on the right end got 1/2' larger.
Bob, thanks for your comments. The enginhouse is just for concept/ideas, I will leave it to Rick to decide how he wants to handle this.
