The invention relates to a production processing method of a subway train, particularly to a method for constructing a station-system beating type production mode of a subway train, so that technical problems that the application scope of the production line is small, the workers grouped based on skill types for working with high variability, the working management is confused, the production efficiency is low, various management measures can not be done truly, and the traceability is poor in the prior art are solved. The method comprises: standard stations are established, a production line of a whole subway train is cut into separate standard stations, when products flow on the production line, workers completes regulated working contents within one beat, and the workers and delivery men are separated by relative stay areas of the products; the time for completing two same products, two same services, or two same batches of products continuously is determined and thus the beat is determined; and then, with a standard station as a working organization unit, production is organized by assembly line work in a beating type balanced production mode.
