Thanks so much turkey hollow rr, and rtr12 for your much appreciated responses!
that dcs book is indeed invaluable, so I will study it more. I believe we bought a z750, so I will use that to power the TIU. Soooo much info in one book! Question for rtr12…
a Lionel powerhouse 180…does it have 2 separate track outs for me to power the variable inputs on the TIU.? Thanks again to both of you!
