Use the existing bench on the right as stub-end staging or a large industry like a papermill or refinery. Mainline runs on the big rectangle. Then you can also ditch the swing / duck / lift section...

i think beachbum has it right about the duckunder,that was the first thing that came to mind when i looked at you plan. if you want to keep all that yard for your first layout, just plan on doing it later. get the main line and a couple of sidings in so you can run trains
