Despite what Don Thompson stated last week about the wheelsets being
interchangeable, I have not found that to be so.
I haven't taken a micrometer to them, but either there is a very slight
difference in length or perhaps in axle diameter or
angle of the coned ends, but I don't seem to be able to get an exact swap with
them.
Each kind has its own merits, so I try to keep a few of each on hand.
