Mike, I think you're making the right decision. I appreciate Tom's suggestion and I think I finally understood what he was saying, but I think it results in more reach issues than you want to deal with. With that in mind, I believe the 1st photo is the latest version of the design. I adjusted a couple of curves in the yard and lead so all the spurs are now straight. The 2nd photo adds Carl's idea for a 45° crossover for going outside through the window and still being able to open/close the window. Note that the changes are color-coded in yellow and can be turned on/off using the Windows and Spur Outside layers. I renamed my file to help keep them straight. 
Some questions that comes to mind are:
How high is the window and where is it located? I wasn't sure, so the crossover may not be in the right place.
I'm still confused about the bridge by the door. Is it a double-track bridge or are there 2 separate bridges? You may have answered that already and I missed it.
Do you want the elevation along the south wall to be raised high enough (5"-6") so a truck can pass under the track or are you okay with it being only 3"?
