On30 easy track

[oldhilinr]

Hello all
 I want to do a layout like my uncle made with his Lionell trains. An oval with a figure eight inside. I seem to remember him using two switches and a 90 deg.crossing for the figure eight.
 How can I accomplish this using my on30 Easy track and what type of switches would I need. How should it be wired.
 Sorry for asking so much, I'm new to this.
