Thanks for the lead! I'll see if I can track one down. There was a really nice 2 rail one on eBay for a number of months several years back and for some reason I never purchased it. I think I was concerned about the flange depth on the wheels, but I'm not sure why as I run 2 rail on 3 rail track all the time and just watch the wheels bump through the turnouts.
