I remember wanting a set of the 15” aluminum passenger cars to run behind my F3s. Then I got a set from Williams. I agree they don’t look great running on 0-31 tubular or 0-36 fastrack. Now I’m just happy with the O-27 cars or the baby Madison’s. Once I retire and build a permanent layout I’ll have at least one loop of O-72 to run them.
Great topic btw for us “traditional “ guys.
