Gallery of plain wheels in order of internal diameter
The images all link to cross section turning diagrams.
Plain driving wheels for locos without bosses for pins are included here (locos with outside frames).
Surface colour differences are partly due to the materials used for grit blasting for removal of the ceramic coating.
