## Finding Stop IDs

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

```bash
# 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 |
| Praterstern | 4205, 4210 | U1, U2 |
| Schwedenplatz | 1489, 1490, 4103 | U1, U4 |
