Unable to answer "What’s the surface here?" for https://osm.org/way/362549068 via StreetComplete 53.3:

There is only a small path where the grass has been trodden down, but the path crosses train tracks, which is illegal and is subject to a fine. I personally think the path should be removed, to avoid personal injury, and people getting fined.
