An integrated control for electric traction railway vehicles particularly suitable for a speed, antislip and power limitation control for a railway vehicle comprising at least one traction system provided with an electric motor which can be operated by an electronic drive system that performs a torque or current control, characterised by comprising a control architecture configured to determine: a) based on signals and/or data and/or commands received through a communication protocol, a difference between a limit power transferrable to/receivable from a power source and an electric power requested by/transferred to said power source, processing said difference with a PID (Proportional, Integral, Derivative) control logic to supply a signal comprised within minimum and maximum limits of a torque or current reference that can be supplied to the electronic drive unit of the electric motor of the railway vehicle; b) based on the signals and/or data and/or commands received, a torque or current signal to be implemented in case a slipping/skidding event is detected, with said signal comprised between the minimum and maximum limits of a torque or current reference that can be supplied to the electronic drive unit of the electric motor; c) based on the signals and/or data and/or commands received, a difference between the desired speed of the vehicle and the current speed of the same vehicle, with said difference processed with PID control logic for the generation of a torque or current signal to supply to the electronic drive unit of the electric motor, said torque or current signal limited dynamically in accordance with the torque or current signals determined according to the logics of points a) and b).
