Thank you Mike, Peter, Bob, John, and Dave.
Mike, you have a great point about the steam engine cab clipping the door of the engine house. If you ran the 773 or K4 when I was at your house, I certainly didn't notice the angled back corners of the cabs. I'm sure I won't again unless you being it to my attention. We will see what I have when I set it all up on a sturdy base, and I'll do whatever is necessary to make things work.
Peter, Jeff Grove of Carolina Craftsman Kits did a really nice job researching that engine house kit as he did on all his kits. The owner who I bought the kit from told me Jeff built this one as the final pro-production run. I'm looking forward to building the station to go with it.
Bob, thank you for working on the SCARM drawing. Yes, if necessary shortening the engine house will probably be the way to go.
John, I know myself too well to know I will overlook something. I didn't want to buy the building without knowing it would fit. In this case I knew I could get the two tracks in. I just didn't think of the wye until afterwards. Somewhere way back in this topic we discussed a turntable and wye and discarded the ideas. Of course this is the 4th plan, the 3rd I started building since January 2107. 
Dave, Thank you for working on the plan also. You guessed correctly on the width and positioning of the doors. I still can't get SCARM to load either yours or Bob's files and can't link to the scarm.info to follow instructions. That's fine for now. I can see from both I can get the track in. I have no problem cutting some solid track sections to fit. I have already done a couple. I have plenty. My flex track bends leave something to be desired. They worked okay for slight bends as needed in the original plan, but I haven't had success with smooth bends. I have one that is a little wavy, but at the angle it is viewed it isn't noticeable, and all my engines have run on it without trouble. Maybe a car will sometime. Yes, this is certainly a compromise on turning engines and storing engines with the same track, but isn't the whole plan a compromise? 
Thank you everyone!
