The invention relates to the technical field of rail transit, and discloses a novel train stop device. The stop device comprises a motor, an output shaft of the motor is fixedly sleeved with a disk, one side of the top end of the disk is fixedly connected with one side of a connecting rod, a fixing rod is fixedly mounted in the middle of one side of the connecting rod, the top of the front surfaceof the fixing rod is fixedly sleeved with a piston rod, one end of the piston rod extends to the interior of a supercharging device, the supercharging device includes a mounting box, and one end of the piston rod extends to the bottom of one side of the mounting box and is fixedly sleeved with a push block. According to the stop device, through arrangement of the piston rod, the supercharging device, the mounting box, the push block, a rotating rod, a push rod I, a rotating disc, a tension spring I, an output rod and a tension spring II, the force transmitted by the piston rod is amplified, ahydraulic tank is compressed by the output rod, greater pressure is provided for lifting hydraulic oil to ensure that the hydraulic oil can reach the interior of a master cylinder and complete the clamping of a rail.
