The invention relates to a 1st power supply arrangement for a rail vehicle. The rail vehicle includes at least one driven car with an intermediate circuit, a brake system and an energy supply system for supplying the brake system with operating energy. In order to improve the framework conditions to ensure reliable electrodynamic braking, the energy supply system contains at least two energy supply units, for the driven car, arranged at the intermediate circuit, for the redundant energy supply to the brake system.

Power supply device for a rail vehicle

A method and an arrangement monitor a brake system of a brake arrangement of a rail vehicle. To carry out such a method comparatively cost-effectively and gently on the wheels and rails, the deceleration of the rail vehicle is detected with a deceleration measured variable being obtained and the frictional connection between the wheel and rail is detected with a frictional connection measured variable being obtained. In the event of a small deceleration measured variable and a normal frictional connection measured variable, an error message signal is generated. In a brake system with at least one brake actuator, the deceleration of the rail vehicle is detected with a deceleration measured variable being obtained and the brake force of the at least one brake actuator is measured. In the case of a small deceleration measured variable and a low brake force, an error message signal is generated.
