Dear Stan

Thank you for the explanation. Colombo time: The heat shrink tubing you over the IR how much does it concentrate the beam to the receiving IR? I have eight loops on one layout that I am planning on building and some will have IR and some will not. I have some parts in house already and balance of the parts on order and are coming from Asia. As soon as I get the part and have some time I will assemble and I sure that I will have more question for you once I get started. I believe that your method is actually cheaper than the isolated track method. Here is my math please feel free to correct me. IE Fastrack isolated track about US$11.00 each you need two. (Yes I know you can cut the rail with a Dermal 5 inch Fastrack US$4-5 each again you still need two) Stan IR special cost about US8.00 if not cheaper per crossing. This is still best DIY project based on price I have seen.
