I have tested this on my automatic train game, and it appears that parts that are close to the player but still likely don’t own seem to be running at 30Hz. The moment that I sit in the train, the train starts moving smoothly again. So it appears to be stepping at 30hz when parts are far away OR they don’t own.

Is this a bug or does it have something to do with the train not being within what is considered as “Clients simulation radius”?
P.S: The train position is set via body position
