Arthur,
Understood. Thanks. Last question: If I understand correctly, the ZW is 275 watts whether used all on one channel or split amongst the four. Correct?
My trains seem to run fine, but when I see all the newer locomotives listed to run at 18 volts, I was concerned when I read 15 or 16 volts on the app. I don't know the tolerance for running out of spec with lower voltage and thought I should do a little research.
Thanks again. Bob
