service status; operational information
Refers to real-time information about whether a public transport line is running normally, delayed, suspended, etc. Common in station announcements, apps, and websites.
I checked the service status on the electronic board at the station.
Due to the typhoon, the service status is being updated as needed.
運行情報 is the concrete information (delays, suspensions) provided to users, while 運行状況 is the broader operational state or condition of the service.
Compound of 運行 (operation, service) and 情報 (information).
