Voice communication system


Internal communication system “Visit”




To ensure the voice communication of the conductor with passengers of the car.

The system consists of a base station, installed in the service compartment, and 12 passenger stations.
Communication of a base station with each passenger is carried out through the two-wire line.


The base station provides the opportunity to work in two modes:

  • voice data exchange mode with any one passenger of the system
  • broadcast mode when the base station transmits voice data simultaneously to all passengers  of the car


The base station call by a passenger is carried out by audible tone, while voice messages can be transmitted only after the reply from the base station.

The system makes impossible to listen to the passengers’ conversations.
