A railroad vehicle communication system according to an embodiment of the present invention includes: first and second transmitters having channel numbers and spaced apart from each other; and a plurality of receivers classified into a plurality of groups, each having a channel number and a group number, and sequentially disposed between the first and second transmitters. In addition, each of the plurality of groups includes a pair of adjacent receivers having the same channel number and the same group number. When the first transmitter, the second transmitter, and the plurality of groups are adjacent to each other, the first transmitter, the second transmitter, and the plurality of groups are configured to transmit and receive operation packets, voice data, and data packets as transmission or destination. In addition, the operation packets and the data packets include a channel number of a corresponding transmission destination and a group number of a corresponding destination. Also, the receivers determine whether to receive or retransmit based on the channel number and the group number. Smooth wireless communication can be achieved without interference by harmonics.
