My layout is wired exactly as Bob described. I use this to tap the feeder wires into the main power wires. Of course, I keep mine red to red and black to black unlike the picture below.
I call them suit case taps but they are called Wire Taps . I have yet to have one go bad on the layout or the boat trailer. On the boat trailer they are submerged occasionally, too.

How many feeders you have has nothing to do with having one transformer. You can have as many as you need. I recommend using no smaller than 14 AWG wire, which you can find in a variety of colors at any home-improvement store. Stranded or not stranded makes no electrical difference and is purely a matter of convenience. You don't need to run a separate pair of wires for each feeder. You can run a single pair around the layout and tap into it wherever needed. You can use a few inches of smaller wire for the taps if that is easier than connecting 14 AWG to the track.

The rule of thumb I use is to have a power feed every 6-10 sections of track. That way, the engine is no more than 30-50 inches from a feed. I also added extra feeds where I have back to back switches(like yards & crossovers). Gargraves sells power connectors that slip into the rail from underneath, they make a pretty good connection. I'm using Ross track on my new layout, and may use a homemade version of them, If I don't solder to the rails--
A Day Without Trains is a Day Wasted
Just for the heck of it I would add two more, essentially placing one 1/4 of the total track length apart. Depending on what type of track you are using the cost of additional connections is very little. Hope this helps.
