FIELD: alignment of track during its construction and repairs. SUBSTANCE: machine comprises a frame resting on bogies, ands stabilizing units installed on said frame between the bogies with a provision for being adjusted for height and loaded vertically by operating mechanisms. Each unit comprises a generator of horizontal vibrations directed across the machine. Mounted on the frame are the drive control unit and track position measuring system which consists of measuring trolleys and reference straight line connected thereto. The machine also comprises frame-mounted transmitter of the distance covered and two level transmitters of which one is located in the front part of the machine and the other one, in the zone of stabilizing units. The drive control unit comprises a comparator and a memory unit connected to which are one level transmitter and the transmitter of the distance covered. The output of the memory unit and the other level transmitter are connected to comparator whose output is connected to the vertical loading drives. The memory unit is designed to send a delayed signal of one level transmitter. EFFECT: improved design. 4 cl, 3 dwg
