Accessory voltage

Not sure what else you need to power, but an inexpensive computer power supply would work for the vehicles and pole lights. It would have  a 3 vdc tap for the lights, and a 5 vdc tap that with a diode would supply the vehicles. The 12 vdc tap will run most anything else that doesn't require ac, including incandescent lights. Feel free to contact me if you would like more info or examples.

Thanks John, the 3vdc from Amazon was the required voltage for the LED lamps I purchased from Model Tech Studios. The 4.5vdc I purchased from Menards with the vehicles, also their requirement. If I got one of these from Amazon it should supply  the incandescent lights on the fueling station?? I’ll wire it in with its own switch like the others. I like that idea, it gives me control of what lights I want on at any time.

If you already have the other voltages covered, your example would work. If you want any future needs covered, this is what I was suggesting:

At 480 watts, you'll never need more. Adding this makes it simpler:

The power supply plugs directly into it and offers all the different voltage taps. This method also saves having to supply household current all over the layout for different voltage adapters. Please realize that I am in no way saying you're wrong. It's just a suggestion, and your method will certainly work for the one accessory you're asking about.

Yes, other voltages are more than covered. It seems what you suggest would have been better to do it all when I started. I’ll just get the one I showed you. Unfortunately now my layout has 4 different voltage supplies.
Thanks for your input, Gene

Most accessories are 14 VAC
