@Baconator Southern This is an interesting layout so far. Would you consider posting the SCARM file? This would make it easier to see more details of your plan, including grades and individual track piece labels. Others could also suggest changes using an actual SCARM file.
From what I can tell, the reach distances from the front left (bottom of the picture) to the back wall would be about 5 feet. The reaches there and to the back right corner to fix derailments or work on scenery would either require climbing onto the layout or making an access hole in the back.
