breezinup posted:I don't have, or at present plan to have, any of the new P&P accessories, so I haven't been following the operational aspects of these items. I have plenty of the older versions for now. However, I know that different accessories often operate best at different voltages, so for best operation it is preferable for each accessory to have its own variable power supply. I have about five old small starter-set transformers, and a ZW, all of which can be used to power individual accessories at their optimum voltages (or that's the idea, anyway).
I'm curious to know how these various new P&P accessories are controlled to achieve their optimum individual power levels.
I agree. The older accessories do require differing voltages depending on the accessory. The newer ones with can motors are an improvement however, as Matt has pointed out. That said, having had a layout full of post war operating accessories at one time, it took me quite some time, usually weeks, to fine tune the voltage and accessory so that anyone visiting my layout could operate it.
