I've removed this campsite and "playground" feature near the tunnel under train tracks.

I've also removed a name from a dumpster and fixed bridge ruins' name.

If you plan to contribute to OSM, check out the wiki https://wiki.openstreetmap.org/wiki/Beginners'_guide

Please don't add unverifiable stuff, don't add things already mapped, like that tunnel. Don't add names to places which aren't officially named and keep the main name in a local language.
