Would you mind if I gave a suggestion? Instead of using adventures wheels for the leading or trailing wheel, I suggest you use push along wheels. They fit on the WR track and even run on it pretty well. The adventures wheel sometimes do not even touch the track and just stay up in the air, which kind of doesn't look good. Another one would be that for big engines like Henry or Gordon, you should use big city engines wheels as they suit their sizes more. Plus the wheel difference between the engines gives it a sort of realism.
