System and method for rail scanning using electromagnetic engines

A system and method for scanning and evaluating a portion of rail operable for travel by a wheeled bogie having a plurality of electromagnetic engines. The electromagnetic engines are generally operable to generate an electromagnetic field that is operable to penetrate a rail. A resulting eddy current may be generated that is further operable to penetrate the rail. As the electromagnetic engines travel along the rail, readings from the electromagnetic field and resulting eddy current may be used to detect differences in the rail as measured with respect to a nominal rail. The defects detected may be head checks, cracks, corrosion, etc. Further, a treated rail section may be utilized to strengthen the rail itself without compromising non-destructive evaluation. The disclosed system and method may be embodied as a computer program product.
