Unable to answer "What barriers are used at this railroad crossing?" – Railway-Road Crossing – https://osm.org/node/619506219 via StreetComplete 63.0:

See https://maps.app.goo.gl/79MFo6pH1UX8cxkz6?g_st=ac as they are none of the options shown here, because it is not a road level crossing, but a private access to the railway tracks, with a pedestrian crossing right next to them.
The street view image will show the whole of this needs redrawing to truly reflect the situation
