ABSTRACT:
An entertainment and public address system especially suited for mass transit vehicles, including a tape recorder on which is recorded information such as music, news bulletins, announcements, and the like, connected through appropriate amplification circuits to speakers for playback within the listening range of the vehicle passengers. A separate public address circuit is provided for the vehicle operator or conductor and includes a switch which, when actuated, connects a microphone of the public address system through the amplification and speaker network and also energizes a time delay network to rewind the tape recorder a preselected amount regardless of the length of time the public address system is in use. Release of the switch returns the system to normal operation whereupon the rewound tape recorder plays back the last portion of the interrupted recording so as to: preserve continuity of the information being perceived by the passengers.
