How do i make hinges continue spinning without motor?

I’m trying to make a train run over a track using normal Roblox physics, but the hinges for the wheels stop spinning to soon and lose all of their momentum. How do i make the train go further still using normal hinges with ActuatorType still being none, and no script. Just purely getting momentum from a track dropping down. Thanks for reading.

If all the Hinges are set to None then they should spin all the time when contacting a surface.

In the Studio settings click the Physics tab and click the ‘Are Contact Points Shown’ button. This will show you contact points between unanchored Parts. There may be friction between part of the train and the wheel causing it to slow down and stop.
Are you using a HingeConstraint for each wheel, or just 1 on each axle? Too many Constraints can cause lag in the physics of a game.
What is the Density of the Parts of your train. If the Density is too high or too low it will affect how it acts on a slope. Too high might create too much friction. Too low may not have enough mass to create a force strong enough to cause the train to roll downhill.

There are a lot of train and cart posts on the forums already. Try searching through those for more detailed answers. I’ve got a couple tutorial model trains in a few of those posts.
