[openrailwaymap] Signal beacons

Dear community, At the moment I’m about to add a bunch of (trackbound) signalling beacons to OSM, but I don’t see any documentation on the wiki. I’m referring to Eurobalises, PZB beacons and Crocodile/TBL beacons. I can imagine that it is not very necessary to tag the beacons at PZB, but at ETCS level 2 there’s not much more to describe the signalling with. My questions for the discussion: • is anyone aware of how to tag this? • if not: do we want to and should we render? I propose to define a tagging system at least for Eurobalises and to render them as yellow dots/squares on top of the blue ETCS railway lines (perhaps with a reference number displaying at high zoom levels). Best regards, Jeroen
