SUBSTANCE: method of pulling contact system cable comes to the following: each rail 6 is read off by means of distance pickup 16 placed over rail and moved continuously in longitudinal direction of track and scanning in plane 20 passing square to longitudinal direction of track. Problem points of measurement 25 on rail defining geometry of switch are recorded as measurement values in polar system of coordinates. Polar coordinates for measurement values are converted into Cartesian coordinates and information is recorded in memory at continuous measurements of distance by means of measuring wheel after which lateral section for switch 1 is calculated basing on recorded measurement values. Actual measurement values are compared in definite points of measurement 25 with preset values of at least two of enumerated parameters kept in memory, namely, width of clearance between counter-rail and running rail, through clearance or state of tongue as to its wear, minimum width between edge of guide rail and side edge of running rail in curve, width of gauge and/or distance between counter-rails or guide surfaces and deviation of obtained values from preset values. In device for noncontact measurement of lateral section or rail-to-rail distance of track, each pickup 16 is arranged in area over corresponding rail 6 being essentially laser scanner 17 for reading problem points of measurement 25 defining geometry of switch which is made for reciprocation at angle of scanning (α).

SUBSTANCE: invention relates to methods of checking and forecasting condition of rail track. According to proposed method, running course of body of track-testing car is measured by means of inertia navigational system installed under pivot of test bogie, and running hunting angle of test bogie relative to body is measured by means of angular displacement transducer. Then, using axle box-rail transducers, distance from flanges of corresponding wheels of bogie to rail heads are measured. Basing on obtained information , running courses of rail lines are calculated as running course of body minus running hunting angle of test bogie relative to body minus running angle of parallel misalignment of flanges of wheelsets of test bogie and heads of rail lines. Then running values of horizontal irregularities of rail lines are found as product of bogie base by deflection of running course of rail lines from running averaged courses of rail lines on bogie base calculated from courses of rail lines. Running radii of curvature of rail lines are found by dividing bogie base by measured increment of course angles of rail lines on bogie base.
