    • The present invention relates to a method and a system for braking a railway vehicle to enhance the energy efficiency. Provided are the method for braking the railway vehicle to enhance the energy efficiency and the system for braking the railway vehicle to enhance such the energy efficiency, comprising: a first step of driving in a revival mode a motor for providing a towing force for running the railway vehicle according to a command of an onboard controller for controlling the driving of the railway vehicle; a second step of, if the running speed of the railway vehicle measured at a speed sensing unit is over a set oil pressure braking entrance speed, making the onboard controller operate the motor in a revival mode and perform a braking operation, and if the running speed of the railway vehicle measured at a speed sensing unit is under a set oil pressure braking entrance speed, making the onboard controller drive an oil pressure pump and perform an oil pressure braking operation; and s third step of comparing the running speed of the railway vehicle, measured in the speed sensing unit during the second step, with a stopping speed, if the stopping speed, stopping the oil pressure pump. The present invention stops operating the oil pressure pump when the railway vehicle stops, thereby saves the power consumed for operating the oil pressure pump while the railway vehicle stops, so enhances the energy consumption efficiency of the railway vehicle.
