I am fussing a bit with powering all my scenic lighting and accessories. Like most folks, I have a mix of regular lamps (Lionel-style incandescent running at 14-18VAC) and LEDs (like woodland scenics pre-lit buildings and other stuff). I guess every light or accessory could have its own wall-wart. But this sure gets into a cluttered mess after the first 15 lights or structures. So the next choice might be to create a "bus" that runs connections around the layout and feed things off of the bus(es). This too gets messy due to the distance between things needing power and the sheer number of connections that have to be accommodated. Also, low-amp fuses or breakers need to protect everything. Those can't just hang off of the wires--they need places to mount and convenient positioning on the bus.
Some kind of distribution system with terminal blocks, fuses, breakers, and junction boxes seems mandatory. I was wondering how you solved this on your layout, whether it has worked out as you hoped, and what you see as "best practices" for this kind of thing on a hi-rail layout.
If you have a chance, please share what has worked for you.
