This paper presents a research tool allowing to determine the state of the load in the drive system of electric locomotives. This tool was used to compare dynamic interactions in the drive system of locomotive EU07, where as a result of the modernization of the existing DC motors were replaced with AC induction motors. Developed models of combined engine were coupled to a rail vehicle model developed in the class of multibody sytem dynamics. Load the system comes from the moments generated by the electric motors and the forces generated at the interface between the wheels with guide rail. Developed mathematical models were implemented in Matlab / Simulink. Numerical simulations allow to determine the load of drive system for various vehicle dynamic states (startup, steady-state operation) depending on the locomotive load.
