The electric power supply equipment of electric railways vehicles of surface is placed vetality twist and lick on the their body.The arrangement of the equipment on the vehicle body determines the variation of the aerodynamic drag.The gusts of wind occurring during the vehicle movement result in additional requests.The case of the locomotive of type LE 060 EA 5100kW moving with the second driving position is analyzed in this paper.For this particular case the components ensemble of the power supply system was geometric modelled in 3D format at 1:1 scale.

The resulted model was placed in air flow simulation doorking video intercom software to determine the aerodynamic resistance.The wind influence is analyzed for five point values of its speed.The wind direction is simulated by eight point values of the angle that it makes to the longitudinal axis of the vehicle.
