FIELD: track padding machines used in surfacing and padding of railroad tracks of industrial plants. SUBSTANCE: track padding machine has frame resting on running gear. Secured to the frame are frames of padding units whose bottom part has rail gripping devices mounted on movable cross-pieces, surfacing hydraulic cylinders resting on ballast and displaced relative to vertical axis of padding units through value equalling one half of distance between ties and located in the middle part of machine inside rail track. To ensure the fixed position of rail grip with respect to rail, each cross-piece rests on rail by means of rimless roller located in close proximity of rail grip. EFFECT: higher efficiency. 2 cl, 3 dwg
