To provide an in-train broadcast system in which guide information is displayed in a radio telephone set in a train, so as to inform proper guide information.

A station base station 10 in an in-train broadcast system 1 which is installed in each station 2 sends station guide information, such as station names to a base station 20 mounted on a train 3 at a closest distance, and the main base station 20 sends the received station guide information and train guidance information that is stored in an information processing unit 22, such as a train current position of the train and train guide information as 'Please refrain from a telephone conversation in trains because it is annoying to other passengers' as the guidance information in a form of text data to in-train base stations P1, P2,... installed in passenger cars V2, M3,... respectively via a controller 23. Each of the in-train base stations P1, P2,... is lined with each digital mobile terminal possessed by passengers through an idle channel and sends the guidance information by a digital radio wave. Each digital mobile terminal 30 converts the train guidance information into character information and allows an LCD to display it.
