Railworks America

I've gotten the rest of the bogie to work, it follows the rails when entering turns. However I have been breaking my head for the better part of nine hours trying to fix the spinning issue. If anyone who Is more knowledgeable than myself could help that would be very appreciated.

This contains an imgur gallery of screenshots of the blueprints and the model with blender and creo.

I'm gonna head to bed though, Ill comb through any responses If I get any when I get back from classes tomorrow.

Possibly a naming problem.
In Blender, you didn't name the geometry objects according to the naming convention. You should include LOD information.
See the dev docs 9.01 "creating an engine". See dev docs 4.03 for naming conventions.

For example, your 1st bogey should be named "1_0500_bo01" and its first wheel "1_0500_bo01wh01" in Blender.

It's rotating the wrong way likely because you have rotated the object in object mode and not in edit mode. I also had a similar situation. https://youtu.be/pzyzQJTpd9w
One solution you could try is by applying rotation by pressing Ctrl + A. I had not attempted this before. Another is to copy the model in edit mode, add an object, in object mode (like a cube), and delete the object in edit mode, then paste the model, in edit mode. If that doesn't work for whatever reason, you would need to redo the model this time rotating in edit mode. Unfortunately I have not made a locomotive so I can't help with the infinite spinning. Hope my solutions help. Good luck!

Ok so I the trucks have stopped spinning about their x axis as the speed of sound, renaming it in blender with the LODS fixed it however, I've run into some issues which are stumping me big time.

-The trucks are no longer turning into curves, and the wheels are no longer spinning
-I can no longer couple regular engines engines to it to shove it around in the scenario editor, it just instantly crashes with an out of memory error code, and I have to place an engine behind it to bump into it to test move it
-When the FM H-16-44 is placed by itself in the scenario it starts moving by itself even with no controls set up or no engines touching it

I've been looking through the developer docs and the TGC locomotive guide and I cant figure out what is causing these issues.
I'm linking both bogie blueprints, the engine blueprint, the simulation blueprint, the blender file, and videos of the various behaviors of the engine now that the bogies aren't hyper spinning.

Here is the link to the google drive with everything mentioned above.

Rotation should be applied to all the wheels and bogies and all rotational axes should be 0. ( In Object mode - Ctrl+A)

If the cab is at the front of the engine (as the videos lead me to believe), the engine is oriented wrong in Blender for Train Simulator. When viewing the engine in the Right Orthographic view, the front of the engine should be to the right. (for TRAINZ, it's the opposite)
