How would I move an part that would loop around a track?

How can I make it so that a model follows the track instead of just going out of it? Smoothly?

What track you mean? Like the train track song?

By that i think he meant like a train that stays on a track or something.

I’d honestly advise CFrames to do this, but i think there are many other methods.

Yes, a train track like one, can you tell the methods?

Try making some movepoints and tweenservicing to them? I’ve never done a train, but i do know that’s a method to do it.
