A "Departure Board" is a display system found in transportation hubs like airports and train stations. It provides real-time information about upcoming departures, including the destination, departure time, and status of each service. This helps travelers plan their journeys and stay informed about any changes. Typically, the board shows various details such as flight numbers for airlines or train numbers for rail services. It may also indicate whether a service is on time, delayed, or canceled, ensuring passengers have the latest updates before they board their transportation.
