On OSM we map what exists in reality, not what we'd like to see. If there is a path crossing a railway track here then we should map it, irrespective of whether or not it is safe. If there are "no trespassing on railway property" signs, or something similar, then we should still map the trail, but tag that section as `access=no`. I'm going to resolve this note, as it is unactionable, with the info provided. If you have more info feel free to reopen this, and provide it.
