The IEEE61375 2-5 (Ethernet train backbone network) which is the next generation of train network protocol is the international standards promulgated by the end of 2010. The CRH3 train network topology which is based on the Ethernet Train backbone is constructed. The train inauguration procedure and the train network initialization is fulfilled. The NETFPGA is built the 4 motor and 4 trailer of CRH3 train network semi-physical simulation platform and successfully implements Ethernet train backbone network communication protocols. A communication model of car equipment and redundancy switching between working network and backup network in the MAC layer is built. The results which come from the simulation testing of the train network platform show the network performance indicators of real-time, packet loss rate, delay. It provides a useful reference data for the design of the actual train network.
