FIELD: construction.
SUBSTANCE: system to control railway track alignment comprises a mobile reference station, a track machine and a device mounted on its frame for railway track alignment. The system includes a unit of information processing, a rope-chord measurement system to measure bending beam in the area of a flattener and a sensor of an angle of inclination for an antenna of a satellite positioning system. The antenna is installed on the roof of an additional car arranged in front of the track machine. The projection of the antenna crosses the device for determination of the spatial position of a measurement trolley placed under the additional car.
EFFECT: increased extent of approach of track position to rated one with provision of necessary smoothness.
