Brake control device for railroad stock has a braking force setting unit to add a braking force command signal for a powered car and braking force command signals for trailer cars and output a composite command signal. A main control device receives such composite signal and generates an electrical braking force. A braking force computation unit splits an error in an electrical braking force equivalent command signal corresponding to an actual electrical braking force with respect to such composite command signal into a supplementary hydraulic braking force command signal for a powered car and supplementary hydraulic braking force command signals for trailer cars and outputs results to hydraulic brake devices of such cars, wherein the command signals of such trailer cars are individual car command signals obtained by splitting such command signals in rolling stock units a plurality of times. Such setting unit adds such command signal for such powered car and such plurality of individual trailer car command signals and the braking force computation unit computes and outputs a trailer car braking force load element in such electrical braking force equivalent signal as a plurality of individual trailer car braking force load signals in response to such individual car command signals and computes and outputs such supplementary hydraulic braking force command signals to such hydraulic brake devices of such cars based on the command signals in such rolling stock units for such cars and a sum of individual trailer car braking force load signals associated with such cars.
