If you run your wires through the metal brackets, be sure you use Insulated wire. I know of many bus wires that are bare! Also as you work think of future maintenance. Wire joints under tables or scenery can be hard to find later.
If you have several "blocks" be sure to put an On/Off switch on each for trouble shooting. I used industrial circuit breakers on my layout. They do trip sometimes!
