Hey Scott,
I live in Cedar Rapids, IA, so we're in about the same climate zone. I built my garden railway in 1994 and made the first connection to 125 feet of track with 12 gauge cord made by Malibu lighting. I had just one connection position and ran with no problem at all for 11 years. In 2005 I added 200 feet of stainless steel at first without adding any connections points. There was almost no degradation in performance except for a small hiccup at the halfway point. I added another connection point and the problem went away. I have had absolutely no problem with the Malibu wire degrading and performance of my locos has been flawless. Incidentally, I run LGB, Bachmann and Aristo locos. I don't have any experience with buried conduit but so far, no problem.
