Hallo!

I noticed the route=historic_railway you're adding are not correct. OSM should not map historic elements, and specifically, this railway now turned into a cycleway.

The relation you added, was mapped initially as this other one (https://pewu.github.io/osm-history/#/relation/1689868), note the tag changes that eventually became into a route=cycling (it should be a superroute, though, but that's another issue).

Gruss
