car. There are also rolling dynamics involved. And under load,
the shape of the bearing and journal, and the materials, makes
a big difference. Kato ASF A-3 trucks for example roll incredibly
well without a load, but as the load increases, the performance
is affected -- it's almost a straight-line correlation.
I roll test every car that I put together, or make ready for
operation. It takes a little time, maybe 20 minutes, to identify
the proper truck design for that model and then find a model truck
and wheelset combination that gives good results. It's makes no
difference to me how well a truck rolls "in theory".
For example, remember those old Lindbergh trucks? Those things
rolled like crazy, we thought they were miraculous in the 1960's.
Oh wait, until you put a car on them. Then your results may vary.
