Really? You're seeing it cross roads with no railway crossing like here https://www.openstreetmap.org/node/185002244?

railway=abandoned is a "route [that] is still visible with ties/sleepers, signals or other railroad right of way signs or infrastructure". Key word here is "infrastructure", which a ROW is not. Bing streetside here https://www.openstreetmap.org/way/141080659 shows no evidence of infrastructure, only a two track through the woods.
