- GTFS-rt trip_id 3889813-26H-__LVE-L-Ma-Me-02 stop_sequence 14 has stop_id 1496 but GTFS stop_sequence 14 has stop_id 1101 - stop_ids should be the same
- GTFS-rt trip_id 3889813-26H-__LVE-L-Ma-Me-02 stop_sequence 15 has stop_id 1592 but GTFS stop_sequence 15 has stop_id 1224 - stop_ids should be the same
- GTFS-rt trip_id 3889813-26H-__LVE-L-Ma-Me-02 stop_sequence 16 has stop_id 1436 but GTFS stop_sequence 16 has stop_id 1496 - stop_ids should be the same
