What is the purpose of passenger service announcements?

The purpose of passenger service announcements is primarily to inform passengers about important updates regarding their journey, including train schedules, delays, and safety protocols. Effective communication during transit enhances the passenger experience by ensuring that they are aware of any changes or necessary actions, such as safe boarding and alighting procedures. Keeping passengers informed helps in maintaining safety and order, as well as providing a sense of security and reliability during travel. This function is critical in public transportation contexts, where timely and clear information can significantly affect passenger satisfaction and safety outcomes. While entertainment, sales, and feedback are valuable in their own right, they do not align with the core objective of communication aboard trains.
