Fast Tracks turnout tolerances are deliberately tight because you don't want wheels wandering on a turnout - you want to control the wheel path precisely for minumum derailments. However, if the wheels are not in guage, then all bets are off - the tight tolerances only work if the wheels are in gauge.

If you losen the tolerances in a turnout to be "more forgiving" of slightly out-of-guage wheelesets, then wheels will be able to wander more in the turnout - and the result is simply more derailments for in-guage wheelsets as well.

Long story short - keep your wheels in guage and use jig-built or scratchbuilt turnouts with tight tolerances and you will have almost no derailments at turnouts except for operator error (run a turnout thrown against you). Commercial turnouts tend to take the "more forgiving" route on their tolerances, with the result being that in-guage wheelsets can wander more and you get more derailments.

Should be able to adjust

I think you can fix those. I will ask our resident locomotive guru at the next session (tomorrow night) about the old Katos and how he goes about getting the wheels in gauge.

I have to get him to help me gauge a N Life Like/Walhters RS 2 I have anyway.

I checked with our guru

He suggested pulling (or pushing) the wheels as you twist in opposite directions. Thats how the gauge the N scale locomotives on the layouts I operate on.

He went on to mention that some early Kato made atlas N (and presumably Kato of the same era) Had a problem where (and forgive my flaky memory) the bushings or axles could crack and cause the wheels to never stay in gauge .. they would keep drifting. If you are finding this to be the problem.. that you cannot keep them in gauge no matter what yo do.. it may be terminal.

Fixing wheel gauge on Aero Train by Con Cor (N gauge)

I have several small hobby flat blade screw drives. I want to understand as I am a novice and paid a lot of money for this Aero Train, I put the small flat blade on the inside of the wheel not the out side and twist to line it up with Kato unitrack, I sure don't want to harm this engine.

Con Cor was going to call me, but I have not heard from Them.

Thank you for your suggestion, as this is the only train I have had a problem.
