----- Original Message ----- From: Jim and Cheryl Martin . . . . . . . . . . what's the difference visually and operationally between code 110 wheels and RP25 wheels? Is one more prototypically-proportioned for S-scale?. . . . . . . . . . . . . . . > > > > > > > > > > > The question make it sound like the world is divided into two groups, those who use code 110 and those who use RP25.
In fact the world is divided into two groups, those who know that Code 110 is one of the wheel treads defined in the NMRA's Recommended Practice 25 and those who don't. Have a look at http://www.nmra.org/standards/sandrp/pdf/RP-25%202009.07.pdf You will see a line called called Code 110. SHS and others use this. Others, AM for instance, sell models fitted with code 126 wheels. Note also the the "code" number is derived from the wheel tire (flange & tread) width of the wheel. Both code 110 and 126 are "scale," as that term is generaly understood in our hobby. Properly gauged wheelsets of either code on propertly gauged track will operate just fine. The narrower code looks more realistic (looked at any real RR wheels lately?) since real wheels have a width of about 5½ inches, which in 1/64 scale would be about "code 086." Highrail is something entirely different. Tom Hawley -- Lansing Michigan ------------------------------------ Yahoo!
