Abstract
The article investigates the possibility of detecting defects in the form of transverse cracks in the rail foot at continuous inspection of rails during their operation. Magnetic method is chosen as an alternative to ultrasonic inspection. Computer modeling was carried out, based on the results of which a working model of the magnetization system and registration of control signals was developed and manufactured. Experimental studies of detection of crack models in the rail foot were carried out in laboratory conditions. The studies confirmed the results of computer modeling and proved the possibility of detecting such crack models. The minimum sizes of detectable crack models in rail foot in the zone of rail fasteners and between them have been estimated.
