PURPOSE:To provide an information transmission apparatus which ensures high cost performance and easy change of arrangement in railway vehicle arrangement where control devices are distributed to a plurality of vehicles. CONSTITUTION:A first information transmission path 20 and a second information transmission paths 21, 22 which are extended to all of vehicle 101 to 105 of vehicle arrangement are provided and the second information transmission paths 21, 22 are extended up to the same range of vehicles as the power feeding range of the auxiliary power supply apparatuses 13, 14. The first information transmission path 20 is connected with the second information transmission paths 21, 22 through transmission converting apparatuses 23, 24 and an integral signal is transmitted to the second information transmission paths 21, 22 from the first information transmission path 20. Moreover, the signal transmitted or received among the apparatuses 9 to 12 is transmitted through the second information transmission paths 21, 22 and apparatus information of each apparatus 9 to 12 is transmitted to the other vehicles from the second information transmission paths 21, 22 through the first information transmission path 30. |
