Railway engine pulling bogies on a splinemesh track with pure physics

Hi,

I managed to get it running using angular motors and physics constraints. However, I’m getting bounciness at high speeds. I managed to reduce it using friction but doesn’t look like a full-proof solution. When I adjust the strength of the angular motor to be too high, the wheels start going haywire even with the constraints.

For the bounciness issue, it’s towards the end of this gif…
