You would think a perfect dcs track signal on a 6 x 4 loop. Somethings not quite right. 

If you're testing  try joining the outside rails with alligator clips. Did you try a track signal test on the loop?

I suppose  remote /tiu/ communications could also come into play,

Anyway  we  figured if we  can get a good signal on one block. Hook up  another and then another . (test as you go) until you end up  as  in our case with 4 tiu in super mode with about 6 or seven scale miles of track.. We have a great dcs signal  over most of the layout..
