I've decided to recycle Layout 2 and convert it into Layout 3. My main reasons are: 1) unresolved issues with signal wiring; 2) vertical alignment issues in the track that cause uncoupling where modules connect; 3) create a more comfortable and usable layout room. In addition, I hope to gain a bit more main line run, increase industry opportunities for pick-ups and drops, and maintain an option for continuous running. The current / old layout (#2) was to follow this plan: Here's the track plan, made using Empire Express 2.0.1 for Mac OS X. I guess it's an "island" layout, with the middle open (so, it's a donut?!).

I never installed the upper deck. Here's what I have right now for Layout 3: Layout 3 Plan, v. 1 by Bruce Adams posted Mar 18, 2016 at 2:17 PM I already see a few issues: 1) too close to the layout edge in spots; 2) a lot of tight radius curves; 3) no clear purpose for industry tracks. Suggestions would really be appreciated. Thanks, in advance!
