A CFrame-based train moving system

[Scottifly]

I made up a physics based train setup that worked pretty well for another “tutorial” post a while back. There is a sample train system in my post that worked really well because it would travel insanely fast with about 10 degree angles in the track sections and wouldn’t derail.
Check it out here:

How to make a basic train

You don’t actually have to have a script with any kind of loop in it. Here’s an example place I put together, with a ‘circular’ track and 2 carriages connected by a RodConstraint. The carriages have 4 wheels with HingeConstraints in them, as well as 2 axles below the track with HIngeConstraints, and 2 wheels between the tracks to keep the carriages aligned. All HingeConstraints have the AcuatorType set to ‘None’. Both carriages have a VectorForce in them which doesn’t require constant updatin…
