how my model should work:
as seen in the picture "curve", my carrier runs from left to right on the blue ties. when it reaches the 90°-curve, the carrier should drive with its right front corner (with its pin on the bottom) into the lane grooves of the curve to turn 90°. The carrier is always driven by the ties as soon as the carrier reaches them.
what I tried:
I tried to handle this with a curved transport surface as in picture "transport surface" and defined the curve as a collision body.
how it runs:
the carrier drives straight from the first ties and passes the curve -> no curved transport
