To meet the demand of high rate transmission in the future train communication network, a Ethernet-based Train backbone network is designed. On the base of analyzing the feature of train backbone network, the software and hardware design of the Ethernet Train Backbone Node （ETBN） is developed. A train network test which can be evaluated the performance o{ the ETBN is proposed. The results show that the Ethernet-based Train backbone network can achieve the high data rate and the high reliability. The proposed scheme of the Ethernet-based Train backbone network is feasible to fulfill the future demands of the train communication network.
