How do you isolate Realtrax (or Fastrack) into blocks on a permanent layout? I know they make a small section already cut, but that could get expensive fast. In HO, I would put all the track down, and then use a hobby saw to cut the track where I wanted to make a block, putting a bit of plastic in the gap to keep expansion from making the connection back. On Realtrax, do you just cut through the center rail and run a wire for the block connection? I could see where you could also just bend the center rail contact back so it did not contact the previous section, but if you want a block to start in the middle of a 30" section, that won't work. Any input on how you did this will be appreciated.
