SUBSTANCE: strain sensors are installed symmetrically in pairs onto a rail. By signals from strain sensors symmetrical and asymmetrical deformations of a rail journal are identified. When symmetrical deformations exceed the selection threshold established as 3-4 times higher than the level of internal noise of measurement equipment, a number of a wheelset is set as equal to one. In the measurement section with length of at least two lengths of circumference of a rolling circle of a new wheel the speed of train motion is identified to detect a frequency band, where frequency filtration of symmetrical deformations is carried out. Every time the selection threshold is again exceeded by filtered symmetrical deformations, another wheelset is registered. Then frequency filtration of asymmetrical deformation is done in a frequency band determined by frequency of free oscillations of a rail. Maximums of asymmetric deformations are registered on each pair of strain sensors. If maximums at adjacent pairs of strain sensors match, they are compared with the threshold of registration of the defect determined by the maximum depth of the permitted defect, diameter of the wheel and speed of the train. If this threshold is exceeded, the registered wheelset is rejected.

EFFECT: improved validity of defects detection.

Cure radii, positions of rail threads in plan and profile, track gage and other parameters related to electronic GPS map to relate them to the data of last trips of track metering train. At a time, strain-gage mounted axles are used to define vertical and lateral forces, their relationship in interaction between track and rolling stock and between rail and wheel. Strain-gage auto couplings are used to define dynamic forces at rolling stock to estimate dangerous section of the track for empty cars to be related to track profile. Proceeding from track geometry parameter measurements and train speed, probability of train derailing is estimated caused by rolling of wheel flange on the rail. Track sections are defined which can have anti-derailing factors lower than standard ones to work out recommendations on current maintenance of said tracks.

EFFECT: higher validity and efficiency of estimation.

SUBSTANCE: invention relates to control over the state of track, particularly, to control over displacement of welded railway rail skeleton section displacement. Proposed method consists in defining the position of markers on rail skeleton relative to fixed objects (reference sleepers). Welded butts are used as said markers. Relative arrangement of selected welded butt with respect to selected reference sleeper is defined by the data of flaw detector car magnetic control channel so that signals from, say, bird pad and welded but can be unambiguously identified on defectogram. Besides their relative spatial position can be unambiguously identified by the data received from track transducer (coordinate meter) of flaw detector car. Magnitude of displacement is defined by comparing current data with that obtained before.

EFFECT: instrumental control over displacement.

SUBSTANCE: invention relates to track safety control and serves for remote detection of changes in track conditions caused by rail structure faults and occurrence of dangerous objects in groundwork. Proposed method comprises recording of vibroacoustic pulses in rail resulted from interaction of wheel pairs with rail joints at equal opposite distances therefrom. Signals registered on train passing said rail joints are filtered out and accumulated. Note here that after passage of first train over known-good track said signals are converted to maximum affinity to conserve parameters of correcting circuit. In passage of the next train of track section - signal generator result of comparison is compared with preset threshold. In case it is exceeds decision is made about availability of affected track ahead of running train.

EFFECT: higher reliability of remote detection in real time conditions.

SUBSTANCE: in this method for determination of longitudinally-stressed state of rail strings for continuously-welded track following is performed: periodical measurement of rail string portions temperature, determination of temperature longitudinal stresses of portions with simultaneous determination of longitudinal strains of portions caused by external force impacts or changes in track condition. From this longitudinal stresses of portions between control marks are determined taking into account changes in their length and amount of longitudinal stresses. Additionally, strains within reference portions including several portions of rail strings are determined, correction factor is determined as ratio between sum of distances of rail string portions within reference portion and reference portion length, and actual longitudinal stresses for each portion of rail string are determined with regard to this factor.

EFFECT: higher accuracy of determination of longitudinally-stressed state of rail strings, lower operation and diagnostics costs of continuously-welded track.

SUBSTANCE: invention relates to controlling continuous welded rail track rail lengths. Prior to laying rail length, stress concentration zone (SCZ) is defined from intrinsic magnetic scatter field (IMSF) by using magnetometer pickup to scan along rail head. Magnetic field scatter gradient Hp (dHp/dx) is defined in SCZ, where Hp is magnetic field intensity, A/m, x is analysed line of SCZ, and obtained data is stored as initial data. Then, rail length is again diagnosed in SCZ to define above said parameters after 50-150 mln t of freight is carried on track and obtained data is stored as data on 50-150 mln t of freight transportation. Obtained data is compared with initial data to define maximum parameters. Said zones are defined as most predisposed to failure. Revealed SCZs are subjected to additional intermittent control. Zones most predisposed to failure are subjected to additional control in case rail length temperature is 50-60 degrees below or 10-15 degrees above that of laying rail lengths. In case defect is detected, it is to be eliminated.

EFFECT: higher quality and validity.
