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.
