PROBLEM TO BE SOLVED: To establish a transmission path between cars for recognizing composition by each composition after division even when the division is performed at an arbitrary part in the composition.SOLUTION: A train information system 1 is provided with: controllers 11 installed in the respective cars; a transmission path 10 for mutually connecting the controllers 11; terminal resistors 16, 18 for stabilizing transmission of the transmission path 10; switches 15, 17 for disconnecting the transmission path 10 to connect the terminal resistors 16, 18; and a setter 12 for setting terminal information showing whether or not front sides or rear sides of cars are terminals of composition in the controller 11, in which the switches 15, 17 are arranged on the front sides or the rear sides of the respective cars in the transmission path 10, the same number of the terminal resistors 16, 18 as the switches 15, 17 are arranged so as to be connected with the transmission path 10 in application of the switches 15, 17, and the controller 11 controls the switches 15, 17 based on the terminal information.SELECTED DRAWING: Figure 1 |
