The removable segment at the balcony door and at the main door of my room have a problem with the track transition.
The tracks are based on wood and cork. At the end are two brass screws at each end and the rails are soldered to them and then cut. That results in a well adjusted transition at the segment ends.

The problem appears after some month or years. The wood and cork shrinks and the track sinks down but the brass screws keep their level stable. That results in "ski jump". I get a nasty click noise if the track is straight but 6 axis engines are likely to derail if the jump is in a curve.
I know other techniques to do segment transitions but the brass screw method is often used, simple to do and well documented but nobody reports problems similar to my ski jump problem.
