Abstract
The heat energy dissipation capacity of the provided dynamic braking resistors for a given transit vehicle is established and then the generated motor current supplied to those resistors by the regenerating propulsion motor of the vehicle during the brake mode of operation is controlled to limit as desired in accordance with that capacity the total energy dissipated by the dynamic braking resistors.
