Well, isn't this not the first node on OSM? I mean it is the node with number 1, which indeed is the smallest number available, but it is at version #39 (2025-01-11) and it's first version has been deleted a long time ago. Since then, the number 1 has been reassigned to a newly created node such as this radio tower.

Please read fix-me! In addition to this, the tag railway=level_crossing is already 11 years old
