1.
operation; service; running (of trains, buses, etc.)
The scheduled operation of public transportation such as trains, buses, and other vehicles along their routes.

USAGE NOTES:
運行 refers specifically to the operation of land-based transportation (trains, buses, streetcars). For ships and aircraft, 運航 (with a different kanji) is used instead.
COMMON COLLOCATIONS:
- 運行ダイヤ (operating schedule/timetable)
- 運行状況 (service status)
- 運行を再開する (to resume service)
- 運行を見合わせる (to suspend service)
- 臨時運行 (special/extra service)
SIMILAR WORDS:
運航 uses the kanji 航 (navigation) and applies to ships and aircraft. 運行 uses 行 (go) and applies to land transport. The readings are identical, so context and kanji are key.
