FIELD: transport.
SUBSTANCE: invention relates to control instrumentation intended for checking railway equipment for serviceability. Proposed method comprises measuring magnitude of axle box displacement in car (locomotive) motion. Said measurement is conducted by simultaneous contactless measurement of axle box displacement relative to bogie and displacement of the latter relative to car (locomotive) body. Note here that said measurements are carried out along aligned axis crossing wheel axle with help of, at least, range finders arranged on bogie.
EFFECT: higher accuracy at higher speed.
