This paper has tested a possibility of securing the braking force in constant power region and the constant torque which is expanded by braking test for small scaled test equipment. Consequently, as securing the braking power with just electric brake in high speed region with expanding the constant torque region and the constant power region, M car can use the pure electric braking because of electric brake of all speed regions. If it is possible to decrease the components which is concerned with air braking decreasing the opportunities to use, the effects of the diminished the weight of vehicle can be expected. The reduction effect of maintenance cost for brake parts can be brought, and the full electric braking in electric rail car can give a good riding comfortableness to passengers, energy efficiency and noise seduction.
