This paper studies the express train transportation organization to ensure that the cargo can be delivered in the shortest time. Based on this, this paper makes the following research: By comparing the characteristics of express cargo and the characteristics of its transportation, the time value of express cargo is studied. This paper analyzes the transportation organization of the express train, introduces the organization of the express train, and divides it into direct trains and transit trains to analyze the transportation organization process. Then, the model of the express train transfer node selection model is established. The model is based on the minimum cost of the train and the sum of the unit mileage cost and the time cost. The conditions for the delivery of various cargo, transportation capacity and traffic flow are constrained. The model and the solution ideas are proposed. The above model is verified by constructing a virtual network and formulating reasonable data. Finally, the stop nodes of each express train are obtained, and the correctness of the model is verified.
