How to make Hinges more stable?

Hi,

I attached 2 Blend files to this post.

Physics_Rail_Test_1.blend works as expected.
The Rails are just animated to move up and down on the Z-axis. No Problem.

However if I animate the rails to move on the y and x axis the system gets very unstable like
you can see in Physics_Rail_Test_2.blend.

Is there a way to “tighten” the Hinges in a Simulation like this?
