Ryaninspiron posted:I personally did not know about that 75ft limit per channel you just mentioned. but you are close on the estimated track length. But I also was not in the club during the construction of the current layout.
Interestingly the branch lines like the subway that runs the perimeter of the layout has the worst issues. In testing on Monday you could hit a horn and it would either not work or get stuck on.
just a guess and not a rule on the 75' !!
G scale can be higher! ( I think I have maybe 150' per channel outside?)
I originally had my whole 2 rail layout on a single TIU channel. It was more than 150' of track. I had my G scale on the same TIU and eventually separated them. So it was suggested why have spare TIU channels not in use? The layout was getting on the fringe of lower signal for any reasons it seemed. So I split it up over more TIU channels. 75' just happened to be the split. I kind of made that my regular here after that.
O scale 3 rail seems to be worse than mine from other posts here. I did set up a 3 rail loop all around my basement. It's on an older TIU with bulbs just on the outputs. The track is MTH Scaletrax with soldered joints. I have around 75' per channel and good signal.
If I plug in my TMCC base and connected to any of my layouts, I have issues there.
That subway line has lit cars that may need chokes? or what else is different? type of track? wiring? length? TMCC equipment?
It would be nice if I lived close to a club like this where I could experiment. I did do enough on my own and was happy to dial it in. I come here to try and share what I've learned when I can.
