A communication apparatus (30) is mounted on a train and forms a train communication system together with a system control apparatus that generates control frames. The communication apparatus includes: a general transfer processing unit (33) that stores a general frame among the control frames; a low latency transfer processing unit (34) that stores a low latency frame among the control frames, the low latency frame being required to be transferred with lower latency than the general frame; a frame identification unit (32) that identifies priority of the control frame received from the system control apparatus and performs control to output the control frame to the general transfer processing unit (33) or the low latency transfer processing unit (34) on the basis of a priority setting table that indicates the priority of the control frame and is set in the frame identification unit; an output control unit (35) that preferentially transfers the low latency frame stored in the low latency transfer processing unit (34) over the general frame stored in the general transfer processing unit (33); and a control unit (36) that performs control to modify the priority setting table of the frame identification unit (32).
