Kevin, the last drawing is from Norm's previous layout where he had his TT/RH in a different location. Carl indicated it's the same TT and RH that you have. My intent was to show you a different configuration vs the long approach in the link Carl posted and to show how much smaller his footprint is. However, if your footprint is larger, perhaps because you have the extended RH, then I would figure out where it fits best. I wouldn't give up the extended RH, I'd design around it. If what you have in your current design is what you need for space, then just move it around to see where you like it best.
I'm not sure which design you think it rock solid, but if it's the one where I moved the yard to the front, I think the yard might be too small, but the grades are all below 3.4%. For the heck of it, I tried moving the grade tracks for the yard to the front. It needs some work and one of the grades to the right side of the bridge is up to 4.5%, but I thought I'd let you see it.
I also attached the RR-Track files for you to mess with. I get that RR-Track is still new to you, but you'll get the hang of it.
