Supporting the whole process of change, we have set up Station Collective Displays in the waiting area to improve passenger check-in. Clarity in announcements and any additional information is gained through the devices of the Announcement System. Included devices such as a controller, provide control and supervision functions, as well as audio signal processing. In addition, the amplifier, is used to provide travelers with audio information about the current implementation of the train schedule plan, including the presentation of deviations from the schedule and other information related to railroad traffic and services of railroad operators. The loudspeakers, which were selected from the wide range of our HUSAR product line, include horn loudspeakers and ceiling loudspeakers, which were positioned in accordance with the current guidelines of PKP S.A. so that the emitted voice announcements could be understood in each zone of the station. The facility was equipped by us with a Time Signaling System, which transmits real-time information.
