The TIUs are powered by smaller power bricks and those get switched on via a master DCS power relay. Then the main and branch lines each have seperate switches and relays that connect the TIU output channels to the tracks when the club has a DCS day. (The club has issues running DCS and Legacy at the same time so only one system is ever on at once now. That should be a thread of it's own.)
I also do not know the exact reason yet. But I imagine one benefit is that they are subject to derail spikes a third of the time. These design choices were made long before I joined and I haven't asked why yet.
I have to ask, just how many TIU channels are connected?
2amp total/.2 amp draw per channel = 10 TIU channels?
I'd guess 75' per channel max for 3 rail so maybe = 750' total track?
I am amazed at the posted differences with signal problems. I run an outside layout of G scale around the yard. I have maybe a couple hundred feet of track on each TIU. I only use the 2 fixed channels right now as it's powered by DC. I added a second TIU when I added another mainline.
I also run 2 rail O scale inside and have a good length of track per TIU channel.
I know some clubs have a ton of track. I wonder if signal loss is more a function of power dips? If the layout is stationary I would believe optimum wiring practices would be easier to achieve here.
