The tutorial hasn't been made yet. It's being worked on, but not even close to finished.
However, the principle is fairly basic. You create the model that you want to animate. Then change it slightly as if it were going to start in the direction you want. Save it with a new name. Again, change it slightly and save it with a new name. Once you have 3 or 4 or more of these models that are ever so slightly different from one another, you use Oliver Pieper's utility
Bin Animater to create the "control" bin. That is what you insert into the track so the game knows how to make it work.
If you are unsure how this works, open the rex bins from c98 in binedit. Start with rex1 and then rex2, etc. You will see how each one is slightly different from the one previous. The combined effect is what creates the appearance of motion in the game.
If you're model will be a simpler, more basic idea, you might want to try using animated textures. You can find some of that info
here Hopefully, we can get something for animated models soon. I can't make any promises right now, but I can say it's being worked on.
I hope this helps.
