Butch, The original powdered (steel) AM wheel sets were indeed #125, I
think it was mentioned that they would run on most anything. Remember
all the initial AM offerings came in a "scale only" version--hi-rail
versions with claws came later. I do think that when Ron started having
things made in China they might have changed to a finer wheel size.
Actually they looked identical to SHS wheels. I would volunteer to
check but my wheel sets have been mixed up considerably and they
typically don't have names stamped on them to check their heritage.
Some of what were talking about also applies to my problem with my AM
Trainmaster that we talked about a few days back. The deeper flange of
the 125 wheel is likely to stay on the track better when it comes to the
various forces that a powered truck impose. While a typical car just
has to ride the rails, a diesel has to keep on the rail, pivot, rock,
endure twisting forces plus pull a trailing load or even worse push a
load. If you ever doubt the forces I'm talking about find an older
Overland engine like the FA or Sd-40-2's. Put the throttle to one
(laying rubber acceleration) and watch it lift itself as it digs in!
