Richie,
Very helpful. The yard is giving me fits. I am not sure if the wyes are helpful due to their length. I am hung up on at least three pass-through lines with O36 switches on both sides and perhaps a storage spur or two near the wall. I view it more as a staging area for a complete train and/or a made up set of cars.
It's good to set your room on a grid (or X,Y coordinates) and create objects for the corner and the support columns indexing them from a fixed point. Then, you visually have the obstructions in the plan. Same for the door and it's in-swing space.
I think you could add some interest to the track plan by twisting the dog bone to create an over/under near the top right corner.
There is also an opportunity to connect the two loops with a bridge for another route.
