This is my current track plan. I recently added a second TIU because I needed a lot of blocks in an area due to lift-out bridges and other cases which created those blocks. After reading Barry's book, I see another option would be to run wires from my other TIU to a remote terminal block, and then branch from that location.
So, my question is: Would removing TIU #2 (an L model), moving it to location TIU 1 (an older TIU), and then just running a wire from say VAR 1 (with DCS on and set to FIXED) to the blocks at TIU location 2 be a better solution? I can use the older TIU to make an engine programming area, sell it etc. Additionally, I can dispense with Super TIU mode and whatever problems that causes.
Downside is that I will no longer have an AIU in location TIU 2. I can leave a transformer there for aux power since the area is fully wired with a common ground, etc.
This is a new layout, so now is the time to figure this stuff out...
Thanks,
Mike
