Would it not be better to be able to get to the wiring by fitting it underneath. If you have twin tracks, you would only need 1 bus wire, with connections going of to each track. Likewise if you have a shunting area with lots of tracks and or a turntable, 1 bus wire can feed all.
Just thinking of practicality for fixing problems or adding extensions/changes later on.

agree to both of you, hanging it underneath is technically the better solution .....
BUT, if you are 65 years old , crawling underneath and working overhead is not that much fun anymore......

Hi Werner,
I sympathise with your getting under a table and working above you. If you think it is difficult at 65, wait until you are 72.
I tried to get all my undertable wiring done before I hit 70 but towards that time I was using a mechanics creeper. ( getting up off it was fun too!)
Still, the best idea is to run the bus under the table if you can.
Cheers and good luck,
Howard.

I am past my crawling days too. A thought that came to me in my insomnia is why not wire on the surface like real railroads. Wires could be run from turnouts, signals, etc. parallel to tracks and bunched together through eyelets or pitons screwed into the baseboard. Paint 'em black and they could pass as cable racks. They would have to dive underboard in some places to be led across the line of the tracks to the outside edge where the control buttons or switches are located. But most of the underboard wiring and hence crawling could be eliminated.

Hello Mikey,

I have never thought of making as you. I find it excellent. I am going to verify to see if it is possible to work like that on my layout

Indeed, it would require careful planning for future potential problems or self-defeating aspects. I've thought of some of those, but not all, so I just threw it out as an off-the-wall idea without any detailed elaboration. If I ever implement it, partially or fully, then I will report.

PS What got me started thinking along these lines is my current 2.8m by 1,2m tabletop (actually augmented desktop) test layout where I try things out for my eventual more permanent layout. There is no 'underboard' access thus there are wires all over the place and I found an easy way to keep them tidy was to group them, where possible, inside offcuts of cable channels that I had lying around, the rubber/plastic cable channels that are used for leading hi-fi speaker or other small cables around the walls of rooms. Big and clunky on an HO layout but better than wire spaghetti, and the principle is there.
