I see the why Martijn would be hard pressed to exclude crossings that are already in the OSM. He's using the Federal Railway Administration, FRA, data as a punch list in this challenge. Perhaps you can add additional features to a crossing in this challenge, if you know that bells and whistles exist at a crossing.
I was thinking of NY State for example, where all crossings already exist in OSM. Those would just be empty tasks. Since they're all points, it should be easy to do a pre-conflation to exclude existing matches.
But I haven't looked at FRA data - perhaps it doesn't include GPS location?
