Maybe give some thought to some sort of over/under action. You have a lot of linear run. Consider a fly over or two.
Mike CT has a fine clean example in a space which appears not as spread out as the above prints.
Also think of cosmetic curves and right of ways which are not parallel to the platform edge.
Variation heightens the interest.
On the track plan below we canted the right of way to run at an angle to the bench work.
Place viewing obstructions to interrupt continuous viewing.
Gracious curves flying over lower tracks can provoke interest.
