The invention provides a heterogeneous network architecture of a motor train unit train. The heterogeneous network architecture is characterized in that a vehicle-level Ethernet comprises a plurality of vehicle-level Ethernet nodes, the plurality of vehicle-level Ethernet nodes are connected in series in a ring network form to form a first channel and a second channel, the first channel is connected with a first network port of a subsystem, and the second channel is connected with a second network port of the subsystem; wherein the train-level backbone network comprises four train-level backbone network nodes, two train-level backbone network nodes are arranged in each of a first carriage and an eighth carriage in each traction unit, and the two train-level backbone network nodes in the first carriage and the two train-level backbone network nodes in the eighth carriage are connected with a first channel and a second channel respectively; and the train-level backbone network node performs data interaction wit
