Finding Stop IDs

Stops are identified by RBL numbers (Rechnergestütztes Betriebsleitsystem). Use the reference data:

# Search stops by name
curl -s "https://www.wienerlinien.at/ogd_realtime/doku/ogd/wienerlinien-ogd-haltepunkte.csv" | grep -i "stephansplatz"

# Format: StopID;DIVA;StopText;Municipality;MunicipalityID;Longitude;Latitude

Common Stop IDs (RBL):

Stop	RBL IDs	Lines
Stephansplatz	252, 4116, 4119	U1, U3
Karlsplatz	143, 144, 4101, 4102	U1, U2, U4
Westbahnhof	1346, 1350, 1368	U3, U6

Tips

1. Multiple platforms: A single station may have multiple RBL IDs (one per platform/direction). Query all for complete departures.

2. Real-time availability: Check realtimeSupported - some lines only have scheduled times.

3. Countdown vs timeReal: Use countdown for display, timeReal for precise timing.

4. Barrier-free routing: Filter by barrierFree: true for wheelchair users.

5. Find stop IDs: Search the CSV files by station name, then use the StopID as stopId parameter.
