Don't worry about code 88 or NMRA RP-25 just ask for P64 wheels and ask them
to use the prototype profile that O P-48 and HO P-87 use (re-scaled for 1:64
scale of course). I don't have any to measure but it looks like Proto wheels
for S scale should be code 87 based on HO and O proto dimensions? As long as
you are buying new wheels anyway if you get true proto flanged wheels you can
then use true scale sized frogs and point spacing and tighten up everything,
it's a lot easier to build proto track than track for larger flanges
