The cart is made with SpringConstraints, PrismaticConstraints and HingeConstraints.

Hello!

Seeing that you have a curve on that rail track that isn’t fully together, I suggest flawlessly connecting each of those individual parts to see if the train runs smoothly.

Thanks for the reply, I managed to fix it by making the wheels really heavy, and making the gravity bigger.
