RP25 contour is not scale specific. But the flange dimensions, and to some degree the wheel width, are. Therefore an HO RP25 wheel is going to have a smaller flange contour than an S RP25 wheel. You have to pull up the different standards tables for the wheels you're comparing and check the different standards to see if they will be compatible. The NASG and the NMRA standards are all available online if you go to their sites. HO RP25 wheels are going to differ from BOTH S scale standards, but will be much closer to the Proto64 standards.
