message from the forest! why does this new loco not stay on track. no problem my shays or heislers.

I have one myself with nary a problem.
How does it fall off the track? Just randomly? Turnouts? Curves?

falls off on turnouts and curves,ithough this loco would run on real rough track,
mine is very good.
How old is the loco (i.e. when was it manufactured?), and what sort of track do you run?
I don’t know the specifics on Mantua, but several older locos have overly-deep wheel flanges which can cause this problem (and by older, I’ve heard as recently as 5 yrs. ago). Especially (as may be the case on logging line) if you’re using lower code track, that may be the issue… Even code 83 track can cause problems with these “pizza cutter” deep wheel flanges…
model is one week old. track is peco code 100.
Check how power reaches the front drivers. On mine, the coupling is a piece of model airplane fuel line (neoprene tubing), which adds considerable resistance to swinging the front engine. The double-pivot hinge link doesn’t help, either (Prototype had a single pivot.) I intend to replace that piece of tubing with a proper U-joint as soon as I can spare the time from higher-priority projects.
I haven’t had any tracking problems on curves down to just under 18 inches, but I’m very finicky about laying track. Also, mine is the wide-gauge version. I don’t know if the HOn3 version has better or worse performance characteristics.
I am guessing your joins, if they are on the curves at all where the problems lie, are not meeting level. They must dip, or the track in general is uneven to such an extent that the rigid driver base keeps the front axle from following because it actually lifts the truck out of the track. If your curves are wide enough for the loco, and if the front axle/truck can pivot easily through 20 deg on either side of front/centre, the dipping in the track can be the only other possibility that I can think of. I found this out with my Lionel Challenger. All other locos had been perfectly content with my tracklaying, but not the Challenger. Moreso, the front truck and lead engine got through turnouts and curves, but they combined, with the trailing truck on the other side of my dipped joins, to lift the rear engine out of the track. At that point it would tend to deviate in alignment outward and fall askew on the rails when the dip passed and the lead truck and engine redeposited it on the rails.
thank you Selector,
your commment is right on the button.
