An information delivery service system that is applied to a passenger train and displays an image for delivering information to passengers, the system comprising: an in-train information display apparatus that groups a plurality of windows of the passenger train and uses the grouped windows as one display area; and a display information processor that outputs image information to the in-train information display apparatus, wherein the display information processor outputs next-station-yard guidance image information, which is guidance image information of a station yard where the train arrives, as the image information, and wherein the display information processor includes: a vehicle-information monitoring device that detects a current traveling position of a train and outputs train's current-position information; and an image-information storing/reproducing unit that specifies an arrival platform for the train in the next station, a side of a vehicle that faces the platform, and stop positions of respective vehicles forming the train on the platform based on a lead-vehicle identifying signal output from an operation control panel and arrival platform information of the next station, stores content image information including a plurality of content image files (31, 32), which are in level of parts, the parts being respectively corresponding to facility information of a station platform, guidance information of a station yard, and stop position information of vehicles, and next-station-yard guidance information including content display-position information of the content image file (31, 32) in stations present in a train operation route, and information of a next-station-yard guidance-display starting point corresponding to the content display-position information, compares the train's current-position information with the information of the next-station-yard guidance-display starting point, and when the train's current-position information matches the information of the next-station-yard guidance-display starting point, extracts a necessary content image file (31, 32) from the content image information based on the content display-position information, to generate and reproduce the next-station-yard guidance image information. an in-train information display apparatus that groups a plurality of windows of the passenger train and uses the grouped windows as one display area; and a display information processor that outputs image information to the in-train information display apparatus, wherein the display information processor outputs next-station-yard guidance image information, which is guidance image information of a station yard where the train arrives, as the image information, and a vehicle-information monitoring device that detects a current traveling position of a train and outputs train's current-position information; and an image-information storing/reproducing unit that specifies an arrival platform for the train in the next station, a side of a vehicle that faces the platform, and stop positions of respective vehicles forming the train on the platform based on a lead-vehicle identifying signal output from an operation control panel and arrival platform information of the next station, stores content image information including a plurality of content image files (31, 32), which are in level of parts, the parts being respectively corresponding to facility information of a station platform, guidance information of a station yard, and stop position information of vehicles, and next-station-yard guidance information including content display-position information of the content image file (31, 32) in stations present in a train operation route, and information of a next-station-yard guidance-display starting point corresponding to the content display-position information, compares the train's current-position information with the information of the next-station-yard guidance-display starting point, and when the train's current-position information matches the information of the next-station-yard guidance-display starting point, extracts a necessary content image file (31, 32) from the content image information based on the content display-position information, to generate and reproduce the next-station-yard guidance image information.
