Passenger Handling System for
Unattended Railway Stations
Filling the need to provide useful communication for passengers at unattended stations, this system allows
automated announcements such as train times and messages for two unattended stations from a remote
location. It also makes it possible for a passenger waiting at the station to use the system's communication
panel for realtime communication with railway personnel for inquiries as well as emergencies.
