Get tramway colors of VBZ (Verkehrsbetriebe Zürich)
[out:csv(ref, colour)];
relation
[operator = 'Verkehrsbetriebe Zürich']
[route = 'tram' ];
out;
Unfortunately, the same line (and color value) are returned multiple times, but we want a unique (distinct) list. The following query will achieve this:
[out:csv(ref, colour)];
relation[operator='Verkehrsbetriebe Zürich'][route='tram'];
for (t['ref']) {
make x
ref = _.val,
colour = u(t['colour']);
out;
}
json
[out:json] returns the result of a query in
JSON format.
[out:json];
{{geocodeArea:Pfungen}};
nwr(area);
out;
The generated result looks something like
