A communication apparatus is mounted on a train and forms a train communication system together with a system control apparatus that generates control frames including general and low-latency frames. The communication apparatus includes: a general transfer processing unit that stores the general frame; a low latency transfer processing unit that stores the low-latency frame, the low latency frame requiring transferring with lower latency than the general frame; a frame identification unit that identifies priority of the control frame and outputs the control frame to the general transfer processing unit or the low latency transfer processing unit based on a priority setting table indicating the priority of the control frame and set in the identification unit; an output control unit that preferentially transfers the low-latency frame over the general frame; and a control unit that modifies the priority setting table.
