Template:Rapid_transit_OSM_map
Template:Rapid transit OSM map
The template generally works if the lines that make up the system have their own Wikidata entries (e.g. S6 (Q7388350) for Zürich S-Bahn), and the entries are connected to an OpenStreetMap line child feature.
Each Wikidata line entity's state of use (P5817) should be in use (Q55654238) and should include the transport network (P16) property (for instance on the S6 (Q7388350) entity, transport network (P16) -> Zürich S-Bahn (Q636091)).
This is a wrapper for Template:Maplink. It fetches `geoline` features and shows them within the template. The template works through a SPARQL Wikidata query. The vital field is `system_qid`, which determines the central item from which all other data is pulled.
First, try this on the Wikipedia page of an item that is supposed to show up on the map (e.g. a metro line):
{{mapframe|frame = yes | type = line | stroke-width = 2}}
If it's not displayed, the item might not yet be linked to an OSM feature.
