The invention provides train Ethernet data transmission equipment and a train Ethernet data transmission method. The train Ethernet data transmission equipment comprises a plurality of train-level switches, vehicle-level switches connected with the train-level switches, Ethernet gateways connected with the train-level switches and the vehicle-level switches respectively, and communication subsystems connected with the vehicle-level switches respectively, the train-level switches are sequentially arranged on corresponding train-level communication buses; the vehicle-level switches are sequentially arranged on corresponding vehicle-level communication buses; the Ethernet gateways are used for receiving messages sent by all the communication subsystems of the corresponding vehicle-level switches and train marshalling information sent by the corresponding train-level switches; and the Ethernet gateways are also used for sending the messages and the train marshalling information to the communication subsystems corresponding to the Ethernet gateways so as to realize train internal data transmission. According to the invention, the efficiency and reliability of train data transmission canbe improved.
