Actually, and If i can find the video, i link it. If my yard is any indicator, there's not much needed to be done as far power is concerned. That is, as long as you have multiple track drops(locations) built into your bus. Basically, if you don't believe in the "only 2 wires for power are needed for a complete layout" philosophy, it's easy.
I already have a very good idea of where to make my cuts on the main. I know that simply because, on my even simply small layout, i ran a drop set if wires to every quadrant of the oval/ dog bone like track side. I also, too the spurs(except one), ran a drop. My yard has one drop, and already has a gap in one of the rails, so I'm good there.
I will then, add additional EB1 breakers for every block. Right now, i have a single breaker/EB1running the whole layout. This actually is a pain because if say, the N loop shorts(is the only one that ever does), the complete layout comes to a halt. Ihave to start and re arm every locomotive(I like lights on). But with blocks, this will not happen, and only the block with the short will go down. The yard is once again a perfect example. I will simply add the EB1in line with the power drop(just cut the drop, screw the wires in, set the jumper for the amp's, and done), and it's done.
The nice thing about the EB1's is that you can add both led indicator light that flashes when a short and shutdown occurs, and a simple pushbutton switch to reset. So it's as easy as seeing a flashing light, looking on the track for the issue, in my case, putting the annoying N wheels back on, and pushing a button, to start only that locomotive and block. Nothing else on the entire layout will have even noticed.
That part(adding the breaker) is easy and very convenient, not to mention, adds a safety factor.
