To analyze the influence of subgrade form on the aerodynamic characteristics of the overhead contact system (OCS) positive feeder in the gale area of the Lanzhou–Urumqi high-speed railway, based on the aerodynamic theory, the flow field calculation model of the OCS positive feeder under different embankment forms is established, and the aerodynamic characteristics of the OCS positive feeder under various embankment forms are simulated and analyzed. The research shows that the embankment height significantly influences the aerodynamic characteristics of the OCS positive feeder. The aerodynamic coefficient of the positive feeder with an 8 m embankment height is 1.3 times that of the 4 m embankment height. The higher the embankment height, the greater the influence on the aerodynamic characteristics of the positive feeder. When the embankment slope rate is 1:1.5, the aerodynamic coefficient of the positive feeder is smaller than that of other slope rates. In the bridge structure, when the windshield height is greater than 4 m, the aerodynamic coefficient of the positive feeder rises obviously. Therefore, when the windshield is set, the height of the windshield is not too high. The research results can further clarify the mechanism of the OCS positive feeder galloping of the Lanzhou–Urumqi high-speed railway and provide a theoretical basis for the prevention and control of OCS positive feeder galloping, as well as the construction of railway windproof engineering.
