I have one of those 0-8-0s that is listed as scale wheeled. I believe it’s stated on the box. A Proto 2 New Haven. I’m thinking the Hi Rail and Scale Wheel are the same model. The wheels are very scale like as far as profile. But the center drivers are blind. 2 pickup rollers on the tender. I’ve run it over a multiple of Ross turnouts and never had an issue navigating any of them.
Just curious for the reason for a chassis or wheel swap ?
