METHOD OF CONTROLLING CROSSWISE PROFILE AND DISTANCE BETWEEN TRACK RAILS, AND TRACK-TESTER CAR Russian patent published in 2011 - IPC B61K9/08 E01B35/00 G01B11/14 

FIELD: transport.

SUBSTANCE: set of inventions relates to railway transport. Proposed method comprises measuring rail profile, track gauge and distance to rails with the help of beams of two laser senders arranged on track-tester car platform above the rails. Measured data is entered into onboard computer memory together with data on run time to determine departure from preset values. Laser senders are secured to turn around. Turn of laser senders is synchronised. Proposed track-tester car comprises two laser senders secured on car platform above the rails and connected via controller to computer. Said senders encased in protective enclosures arranged to turn relative the axis perpendicular to lengthwise axis of senders and are connected with, at least, one drive, e.g. hydraulic cylinder with rod.

EFFECT: higher accuracy of measurements.
