A train data communication system using a railroad is provided to perform high speed data transmission by using a repeater and to prevent the influence of the length of the railroad and external environment. In a train data communication system using a pair of railroads(10,11), the railroad is divided to a plurality of sections and at least one repeater(100a,100b) is prepared in each divided section. A data transceiver unit(50) modulates data by using a carrier, and performs data communication by transmitting the modulated data to a receiver through the railroad. The repeater amplifies the modulated data, and provides the amplified data to an adjacent repeater. |
