@jonnyspeed posted:Depends on how they flange/blind the drivers. The HO model that Bachmann makes requires 22" which is ~30" in S. Could be less if they blind more drivers.
The PFM HO model will go around 18" radius and all its drivers are flanged like the prototype. The Bachmann models have the center driver blind. It all depends on tolerance.
But a Russian Decapod in S is snowball in heck territory. After two false starts in the past, I doubt we'll see one. You won't see one from Lionel because they haven't done on in O. MTH has the files, but who knows those will wind up.
