You're right on the money, Nate! Converted my entire Great Northern 1929 Empire Builder, and it ran great! Unfortunately, I had to convert my cars back to the original MTL couplers. I tried the MTL True-Scale Couplers which was a very easy conversion. However, N-Trak modules vary too much, and the couplers wouldn't stay together. So I'm contemplating going to Z-scale couplers.
