This paper presents a train communication network architecture based on the industrial Ether-net. Based on the actual train traffic modeling as well as the Ethernet network train communication simu-lation modeling established by using network simulation software OPNET,the key performances were stud-ied such as the critical delay,network load,packet loss rate and the ultimate flow of the vehicle Industrial Ethernet in the process of high - capacity information transmission. Simulation results show that a reasona-ble setup of network parameters can make the Ethernet to meet the train communication network band-width and data transmission delay requirements,which shows a full feasibility to use the Ethernet network for high - speed train system.
