Please help me figure out the track plan from this photo

Two tracks in a figure 8.

It just looks like a dogbone because the figure 8 is folded on top of itself making it look like four tracks.

Two of the return tracks run through the tunnel(s) on the viewer’s left under the upper return tracks which cross over those tunnel return tracks.

No reversing section, probably, as the return loops form a figure 8. Shame if it really is three rail…

That is ln the cover of the book. "Top 7 layout trackplans for a 4x8. ". So a track plan does exist. Althouth that doesn t look like a 4x8. Unless it is n scale. If you look in the lower right corner, you can just make out what looks like a dark streak between the rails. Probably the Marklin contact nubs on thier track.
