Tips

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

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

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

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

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