In OR (X2193) I see this derailed bogie of the MSTS Dash 9:

...driving at this short MSTS route (2.5 MB download): bogie test route

Anybody who see the same derailed bogies at the linked route? Any ideas how it comes to the stiffen bogies?

It's ether a hierarchy issue or axis issue, although it could be both.
I've also found that too many parts per truck can cause problems, too.
It's a modeler's problem. If you're not the author, you're stuck with a bad model.

:oldstry:

It applies to all vehicles with bogies locomotives and wagons. In the pictures you see the "Dash 9" originally delivered by Microsoft Train Simulator. It is just an example.
It seems to me to be rather crucial that the route have very few shapes, no signals etc. No other shapes except multiply curved tracks "A1t45dYardCrvRgt.s" and maybe a switch (Example route see my post #1).
I always get the effect when I create a new small route with the MSTS-editor and drive on it.
The same vehicles operates fine in OR on expanded routes. That is why I only noticed it on a short test route.

Meanwhile, I've found out that the stiff bogies only occur if the rails were installed at a height of exactly 1 meter. Rails of that height you get when you create a new route with flat tiles which lie flat in the standard height of 1 meter.

So it has nothing to do with the amount of otherwise built-up shapes in the route as I surmised before.

I think it's a bug, even if it rarely occurs.

Bin fixes this issue, with the bogies turning the wrong direction when backing the engine. And that's why we don't need reversed engines anymore either!

[jonas]

Maybe that BIN solves problems with bogies any way, but here it's about Open Rails (version X2227 and lower).
The screenshot and the video above are made in OR Version X2193. I stil see the same stiffened bogies in todays Version X2227.
I'm not reporting here about a backward setted engine in MSTS BIN!

The facts as pure as possible:

-build a new route and lay curved rails exact at a height of 1 meter (the standard height at new routes)
-start Open Rails and take every vehicle with bogies you want. You wil see stiffened bogies running at the curves

Meanwhile tested: It also relates to tracks at a height of 4.0 meters. So it seems clear to me now that every track which is layed at a height where a 0 stands behind the decimal point causes stiffen bogies in OR (Version X2228).

Thanks for all this detective work.

I've been able to reproduce the problem using the default GP38-2 on a small test track that steamer_stn built recently and reported it at https://bugs.launchp...or/+bug/1318016
