I agree. I prefer metal wheels for various reasons; but was really
surprised at the findings.
In his rollability testing, Brian used the same box car with the same
trucks, swapping out the wheelsets for the tests. So the only variable was
the wheelsets themselves.

A lot of factors influence performance - metal or plastic, sintered or
machined metal, machined brass or machined nickel silver, dirt or oil on
the track, pointed or shoulder journals, fat taper or narrow taper, metal
or abs or delrin sideframes, equalized vs nonequalized, sprung or
But all else being equal, my experience is that metal wheels outlast and
outperform plastic wheels by a huge margin in HO scale. If you think about
the physics of wheels on rails, the weight of an N scale car per square
centimeter of rail contact is far less than it is for HO scale cars, so
direct performance comparisons are not meaningful between N and HO scales
(or between HO and O, or O scale and 1:1)
Then add car weight variability to all that to really confuddle things!
On a related note, the Jul/Aug issue of N Scale Railroading magazine had an
