Here are the details: 1. The sizes of each line is roughly 36' x 24' (theres two running parallel) 2. I used Lionel Fastrack 3. The lines are not connected together 4. I only have one CW-80 transformer wired to each line 5. I am using a CAB-2 to control the Legacy trains 6. I can run 3 trains on one line and 2 trains on the second line (not perfect but it works). So i'm planning on crating multiple "blocks" and connect both lines Should I purchase one ZW-L transformer which will give me 4 possible blocks or multiple 135 watt bricks for each block?

My advice is to buy the biggest transformer you can afford. You might make changes in your layout in the future adding more track & trains. Keep in mind the power draw for your individual trains and whatever accessories you may have/use. So Go as big as you can... Use lots of feeder lines to insure your voltage is constant.
