In the case of electric railway vehicles of surface, the equipments which allow power supply are placed on their bodywork. The mode to dispose these equipments contributes to increase the resistance to motion of the vehicle due to the variation cross-section area. Gusts of wind that occurs during the movement of vehicles lead to increased aerodynamic forces. As a model analyzed, we considered the situation determined by the dispose of the equipments supply on the body of electric locomotive type LE 060 EA of 5100 kW, when such a vehicle is travelling with the first post station in the driving direction. The equipment’s components of supply were modeled geometric at scale 1: 1 in 3D. The obtained assembly was imported in an air flow simulation program to determine the aerodynamic resistances. To observe which is the influence of the gusts wind regarding the resistance to moving we considered five point values for wind speed: 5m / s, 10m / s, 15m / s, 20m / s and 25m / s. With results of the simulations we performed a comparative analysis.
