Is there any way to prevent the part from being put to sleep by LinearVelocity?

Hi, I am creating a train using LinearVelocity and I am having a problem with the model going to sleep and not moving when the velocity is 0.
You can see the details in the video, but it seems that only the car the player is on is active, and the model wakes up little by little due to factors such as opening and closing doors, or operating the controller. Of course this is not the desired behavior.
This train has one LinearVelocity per car body.
Is there any way to wake up the parts the moment the LinearVelocity velocity is changed?

Are the train carts anchored when doors are open? In my experience, using the linearVelocity or similar needs the part to be unanchored, since it moves part physically in-game.

I can’t explain it well, but the door is not anchored in any particular way because of the animation controller.

What about rest of the carts? While doors are open select all carts children and check the anchored section.

This train does not anchor at all in all.
