Dennis,
The Lake County Model Railroad club is just down the road from you, in the basement of Tony's Barber Shop on main St. in Wauconda. We have converted to DCC operation, and you could see how it is wired. There's usually someone there Wednesday evenings, and Friday evenings. The club is HO, just in case that's your scale. You miight also be interested that a new hobby shop has opened, on Milwaukee Ave. in downtown Libertyville.
Pete.
