Being something of a newbie to trains, all of my wheel sets are the new
Super Friction Specials (nice phrase, that :-). After making the mods to
get them rolling smoothly, the only place that seems to exhibit wearing is
the "needle bearing" on each end of the axle. I'm wondering if the
needle bearings on your wheel sets eroded to the point where the
metal axle started contacting the six points indicated in this photo:

That alone would cause increased friction. But, if these eroded
enough and created a deep groove, then this would allow the wheels
to ride higher and higher until the edge of the wheels eventually came
into contact with the frame.
So, I'm wondering if your wheel sets have a groove in the
spots indicated?
