An initial announcement must be made if a train has been stopped for at least ______ and additional announcements must be made at ______ intervals thereafter.

• A. 2 minutes / 5 minute
• B. 3 minutes / 10 minute
• C. 4 minutes / 8 minute
• D. 1 minute / 2 minute

Answer: (D)

The key practice is timely passenger communication during a delay. An initial announcement should go out once the train has been stopped for at least one minute, and then additional updates should be provided at two-minute intervals thereafter. This pattern keeps passengers informed without making them wait too long for the first notice and ensures they receive regular status updates as the situation develops. Alternatives that push the initial announcement to 2, 3, or 4 minutes or that lengthen the update interval to 5, 8, or 10 minutes would delay essential information and reduce the frequency of updates, leaving passengers uncertain for longer.
