One trick to make it look a little less cluttered would be to raise the town/siding above the left end of the ovals. The mainlines would enter tunnels at that end, and break up the appearance of an oval.
This sounds like a good idea. Do you actually mean to raise the track so that the siding would rise up on a grade ... but wouldn't that be too steep? Sorry if I'm misunderstanding here!
I'm open to adding some tunnels to break up the oval affect and add more visual interest.
