Steam Problems With Turntable At Bremen Hbf (track Running Through And Fall Through Ground)

When rotating the turntable at Bremen Hbf there was track running through the turntable. And I was able to fall through the ground beside the turntable.

 

In Chemnitz, there were times when I couldn't move.
I've also had experiences like flying into the sky, like in the picture.

 

Yea, I don't think it was actually meant to be operational. I don't think there are any services that use the turntable, so it was left incomplete since it's not used anyway
