Dan,

If you double gap at all the red stars, two things:
1. How far is it from the red stars on the right and the red stars on the left?? Will this be longer than your the powered locos and lit cars, if any?
2.? For the blue box on the left, is it longer than your train and lit cars?
?
If everything passes the longest powered train tests above, then double gap at all the red stars.? Forget the blue boxes around the stars on the right.? For the large blue box on the left, connect that track to the same track bus as the rest of your layout.? The section of track between your automatic reverse section controller.
