This paper reveals that the problem for division of labor of yards in a railway hub can be decomposed as two levels, which are operation site choice and route choice in the hub. Based on actual data, two optimization models for operation site choice and route choice are built, and the relation between two models is presented naturally. According to the characteristics of an NP-hard problem, the main measures for solving the models by a genetic algorithm are put forward in this paper, and a numerical example is tested on a real railway hub in China.
