Understanding Digital Screens on Trains: Their Functions and Information

For passengers on the Stainless Steel New Generation trains, the presence of digital screens inside the carriages is likely a familiar sight. These screens display various journey updates that are continuously refreshed while the train is in operation. The digital screen is known as the Passenger Information Display System (PIDS). This facility helps passengers access travel information more practically without having to ask staff. So, what information is displayed on the PIDS screen? Referring to information shared by KAI, the Passenger Information Display System (PIDS) is a digital information system installed in the Stainless Steel New Generation fleet. The system is designed to convey journey information quickly and is updated automatically throughout the trip. With PIDS, passengers can monitor the progress of their journey in real time. The information displayed includes the passenger’s seat location, a no-smoking area visualisation, toilet indicators, the next station stop, Estimated Time of Arrival (ETA), current cabin temperature, the current time and date, the train’s name, class, and sequence, the conductor’s name and number on duty, and a route visualisation or journey timeline. According to KAI, the presence of PIDS is a facility that helps passengers obtain travel information more easily, from the train’s position and estimated arrival time to cabin temperature and staff details, all accessible via a single digital screen system inside the carriage.
