RP25 & ScaleSeven Wheel Comparison
?
This shows a comparison of the NMRA RP25 110 wheel profile commonly used for O14 and the ScaleSeven wheel profile for standard gauge locos, established from published web sources.
Given that most narrow gauge locos had a similar flange profile to standard gauge locos often with a slightly narrower tread, the profiles compare well enough for the RP25 wheels to be used for exact scale modelling.
