RTR thank you for the advice. I also like the MTH blocks. I did not know about the 10 amp rated switches for switching power. I have to check the ones I already have. I don't plan to use an AIU as of now. (no automated accessories). The fastrack turnouts will run off track power. The newer ones I purchase will probably have the command control option if I choose to go that route. I was also thinking 3 channels, but if I can get it down to 2 channels that would be better. Have to tread carefully on that one. Your help is greatly appreciated. Thanks, Fred
You are welcome. The 10 amp (or more, more is better) switches should assure you never have problems no matter what power you use for your track or how much power your trains draw. The TIU channels are 10 amp rated and I think that is also the largest available output for a single power supply.
Two channels would probably be fine. One for your outer loop and one for your inner loop, yard tracks and reverse loops. Although my layout is smaller, I have 4 spurs and 2 on my inner loop and it's set up with two channels, one outer and one inner.
I don't have a Z4000, but aren't they 10 amps per handle or close to it? I think you would be ok with one handle per TIU channel (and loop of track). You could switch off the parked trains when not in use. The trains I have, all command control, only use about an amp per engine with smoke on, so I never get close to my PH-180s 10 amp capacity. I don't have any passenger cars, but I do have a lighted caboose or two, searchlight car and some things like that.
