Zusammenfassung:	An in-car information display system includes a power storage device (8) including a storage battery charged with direct-current power obtained by converting electric power from an overhead wire, a plurality of display devices (5B) (5B 11 , 5B 12 , ...) that operate by receiving supply of direct-current power from the power storage device (8) and provide a guidance display related to a service of a train to passengers, and a terminal device (4) that operates by receiving the supply of the direct-current power from the power storage device (8) and delivers to the display devices (5B) information for guidance display that is information used for the guidance display. The power storage device (8) switches a power supply operation to the display devices (5B) according to a residual capacity of the storage battery and reduces a total amount of electric power supplied to each of the display devices (5B).
