The efficiency of both types of electric braking for electric trains for transporting passengers, including for high-speed trains, is shown. We considered two main variants of rheostat brakes that use independent excitation of the traction motor, whi

Recuperative braking of electric rolling stock in railway transport provides energy recovery of the braked train to a contact system. However, during dc electric operation, this possibility is not exploited to the full extent. This is due to the fact
