Fragwürdige Änderung, wenn man im Wiki liest:

> Abandoned:
> The rail has been removed and the right-of-way may have been reused or left to decay but is still clearly visible, either from the replacement infrastructure, or from a line of trees around an original cutting or embankment.

> Can also be used together with highway=* (e.g. highway=cycleway) to tag paths or roads on former railroad lines.

Replacement infrastructure sind hier nunmal Teile des Ruhsteinwegs.
