Sai às 09:00.
It leaves at 09:00.
Language note: Common pattern: “Sai às…” / “Parte às…” Both work; “sair” is more everyday.
Culture note: If you’re asking staff, giving the time first can help: “O das 09:00 sai de que linha?” (Which platform does the 09:00 leave from?)
Context: The clerk gives the full sentence with the time.
