Some background here. This layout started in 1999. It was all conventional with lots of blocks, relays, etc. Then I purchased a TMCC engine and installed that system. Lots of fun on a three level layout. Then in 2002 I purchased my first MTH engine and installed the DCS system shorty thereafter. I purchased most of this stuff from Phil Klopp at his hobby store and he was most helpful to get this stuff installed and operating. I do believe Phil and I did some learning together. There was no Barry's book back then and a lot was being learned about these systems.
Anyway, here's where my layout is today. I have four separate loops that are isolated electrically. I use 2 TIU's in the super mode. They are rev L and 4.3 I believe. I use 2 remotes and they are 4.1. Each loop has 2 channels to power it and the input to each channel comes from different transformers. I'm bearing my soul here, but this has worked for me and worked well for over 10 years. I have run as many as 15 trains at the same time.
I really do appreciate Barry's input here and would like comments on my plan to improve the safety part of this. I plan to power each loop with one transformer. I'll disconnect one transformer from the TIU channel and then simply install short jumper wires to that channel on the input side of the TIU from the remaining transformer. I believe it's the multiple transformer thing that raises the safety concern. Maybe I've been lucky, but I'd rather be safe.
This latest little engine blip, may turn out to be a blessing.
