Train system help

#1

Hello!
I am in a problem where I have a 1 carriage train that can drive perfectly on this track system (glider train system) however, when I add another carriage to it, it derails on any part of the track. It is most common on curved track however, it can happen on straight track as well.
The train used is a glider loco with 2 carriages in-between another loco at the end (all connected with rope). I have tried using different constraints to connect the carriages, amending the gliders, changing the track system over and many other things however, the problem still sticks the same/in some cases, gets worse. (The track system will be linked below being coloured oddly to be seen better)
Another note is that the majority of the train is un can collided except the gliders itself that shouldn’t derail due to them being fully enclosed in parts.

Thanks!

Is the colourful thing on the right the glider?

No, it’s not the glider, it’s the system that the glider drives in

I am a developer at a British transport simulator, and we also use gliders. We use a 16-sphere system consisting of 4 spheres around the rail on all sides, instead of the wheels. So far there have not been any problems with it. Maybe try our system instead?

We’ll try it out! I will mark this as a solution if it worked! Thanks in advance!
