What information must crew members of a delayed train inform passengers about?

Crew members of a delayed train are required to inform passengers about the cause and duration of the delay. This is crucial for maintaining communication and transparency with passengers, as it helps them understand not only what is happening but also how long they might be affected by the disruption. Passengers appreciate receiving information that can help them make informed decisions about their travel plans.

By providing the cause of the delay, the crew can alleviate frustration or uncertainty that passengers may feel about being held up, and understanding the expected duration can help them plan accordingly or make alternative arrangements if needed. Keeping passengers informed fosters trust and helps manage expectations during an unexpected situation.
