All of the trains contain an audio system, which announces the stations and transfer opportunities to other Metro lines. At Arsenalna station, there is an announcement for museums in the area. In addition, most of the older trains are fitted with an overhead video information system, which provides visual information to passengers regarding the current and the next stations and transfer opportunities between lines. While the train is in transit between stations, the system displays advertising (both in video and ticker forms), recreational video content, and local time.
