That may be the reason. But the first priority in design is to make the model operate properly under the stated conditions - apparently O-36.

While the model may have issues with O36 turnouts, do they not run OK on O36 curves?
Judging by Paul's analysis, it would appear the issue is more with the O36 FasTrack turnout. And who is to say the engineering samples didn't work properly on a turnout mounted on a hard flat surface in engineering rather than a carpet?
