Hello All! I'm a bit of a newbie when it comes to electrical work on my layout. Here is my situation: I'm building a layout, starting with one loop (6'x10') of Fastrack and later adding a second inside loop and some spurs. All but 2 of my engines are conventional (2 are Lion Chief Plus 2.0). I've read some articles and watched a few video's from Lionel (about 8 years old) that indicate the following:

Switches - work best at 14 volts. If you go up to 18 volts the lanterns may get hot and melt.

Uncoupler track - works best at 10 -12 volts and NOT to use the accessory terminals on the CW-80 transformer

So if I'm running my conventional engines the voltage will fluctuate depending on the speed of the engine, while the LC+ engines will use 18 volts constantly. These devices will be used using the remote switches that come with them, not by remote control (LCS/TMCC).

I guess I'm trying to decide how to power these accessories independently of the track power. My current power supplies consist of a CW-80, a post-war ZW transformer (the one with 4 handles) and a couple of the plug/play power supplies that you plug into the wall and use the circular plug into the track itself. I don't know if I get one separate 14 volt power supply would that be OK for both accessories? As the layout gets bigger I'll have more of both, but that will come later. Any suggestions or comments are welcome!

Thank you!

Mike

Thanks for the info Rick! But if I'm running my conventional engines the tracks won't be a constant voltage. So the track voltage will be variable. And i don't run TMCC Legacy so I'm guessing I need to utilize a second power source for my switches? Can I use my post-war ZW transformer ad set one of the handles to a fixed 16-18 volts for the switches and use the CW-80 for the track power?

On my semi-permanent layout, I switch between conventional and Lionchief Plus.  As not to have any worries, I just power the four switches with a separate transformer and wired them according to the switch's manual.  Although I believe I had to remove the wires to the outer rails as I was having a "shorting out" issue and this fixed it.

You don't need anything but track power for your switches, conventional or LionChief. They won't overheat, and will work fine on 6-18 volts, as they actually run on just 5 volts internally anyway.  Is there some specific reason you feel you must use the ZW for the switches?

Rob,

Thanks for the info! With regards to the ZW transformer I was thinking (remember, I'm a newbie to electronics here) that I could use the two outer controls to power the 2 track loops (one loop now, build up to the second later) and they could be either 16-18 fixed volts for the LC or variable voltage for the conventional engines, and use the two inner controls for fixed voltage (10-12 for the uncoupler and 14 volts for the switches). Just trying to find the right setup here. I just find that the actual people running these are running them slightly different that what the users guide say. I just don't want to ruin any of the electronics.
