Passenger emergency alarms, also known as railway telephones, are communication devices installed in train carriages like subways and trains. They enable passengers to directly contact the driver or ground control during emergencies by pressing a button. When the “Talk” indicator light illuminates, passengers can communicate via voice with the driver, who responds through broadcast or video systems. These railway telephones ensure quick and clear emergency communication for passenger safety.
