I would like to benefit from the experience resident on this forum. I know that several of you have been in my position before. Here’s the situation. I am building a large, three rail layout. About 1100 feet of track is involved on three connected tables. Table 1 was completed first with switch tracks connected to the first five AIUs and the trains were controlled by TIU #1 or by Legacy/TMCC. Then track was laid for Tables 2 and 3. Although there are still some track issues to smooth out, I am able to run TMCC/Legacy and DCS trains over the entire layout. TIU #2 (and the four AIUs connected to it) has not yet been powered up. I have connected the switch tracks on tables 2 and 3 to the AIUs associated with TIU #2. Yes, there are about 90 switch tracks on this layout.
I think I am about ready to power up TIU #2. I think I understand the procedure described in Barry’s book, but I want the final result to look like the attached drawing. I want the current TIU #1 to end up being TIU #1 again. I’m not sure why that is important to me, except that it makes more intuitive sense to me.
After I have successfully configured the DCS for this layout, I expect to make them all super TIUs.
Since the AIUs are hard wired to a TIU, do they care what the name of that TIU is? That is, if I follow the guidance in Barry’s book, then the TIU shown in my drawing as TIU #2 will be named TIU #1 when it powers up before it becomes a super TIU. And TIU #1 in my drawing will be renamed as TIU #2, as per Barry’s guidance before it is renamed as a super TIU.
I don’t expect to ever add any more TIUs or switch tracks that would require any more AIUs. Can I follow the guidance in Barry’s book explicitly and get to where I want to be?
