I thought P:48 was a combination of correct track gauge and accurate wheel profile. Then it is supported by a higher degree of modeling to correct and accurately scaled details then that on out of the box mass production models.
The statement on the Proto 48 Modeler website appears to support my impression:
"This e-magazine is focused on standard gauge modeling. Proto48 defines a gauge and wheel profile for locomotives, cars and track but it also expresses a concept of finescale modeling. Our models start out with the correct gauge of 4' 8 1/2" and scale AAR wheel profile and continue throughout the model to create an accurately scaled replica of the prototype."
I really would have a hard time considering unmodified old Pola/AHM or Atlas/Roco models equipped with P:48 trucks and Kadees with no other changes as true P:48 models. Or even contemporary mass production O Scale models from the likes of Atlas, Lionel or MTH.. Closer, but no cigar.
I really admire those folks on the P:48 Modeller website for their fine craftsmanship. They have attained a level of modeling that I simply do not have the patience for.
