Power supply
Alan:
look at the voltage drop in the calculator above and below. Use 12 gauge wire.
Alan:
Here's a thought for you... Using these you could afford to have many of them spaced around the layout. That would allow small gauge bus wires and almost no measurable voltage drop.

Alan:
One more thought and then I will stop. I promise. ::)
Anytime multiple switch mode power supplies are used in a parallel configuration (which yours will be when a wheel bridges the rail gap) you should put a high current schottky diode in the positive supply lead to isolate the voltage regulation sections of the power supplies from each other else strange things can happen.

Yes, the power supply could be placed in the corner, any of them.
Imagine the basement is a square, with the 7x8 bump out at the top, I thought of putting the power supply at the top, so I could power the helix and have 3 bus lines (1 for each level) going in each direction from there.
I appreciate the replies!
Thank you!
SD90:
If I use more than 1 power supply, can I just insulate both rails?
