That is exactly the feedback I needed--particularly about #4 switches being better switches in a yard-- and the fact that backing through #4's is better than 064's. I also had not thought about using larger radius curves as transition curves. I think the parallel trackage will look much better. The three tracks inside the right most return loop are for an engine service facility. Would you say that those should be #4's as well-- instead of 072's like I have now?
I really appreciate all the help.
The $100 bucks I spent for the RR-Track program is probably the best money I have ever spent. How you would draw all this up, and keep making changes using paper would be tough.
