How to wire EZ track layout?

[msmx2]

Hi there, I'm new to EZ track and I am wondering how to wire the 4' x 12' layout I have below.

Should I get a 5 amp booster? How does that work and get wired? Any other suggestions?

I've built my benchwork, added my foam and will be painting it tomorrow. Track work is next so looking for some help.

Thanks, Michael
