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.

Disclosed in the present invention are a permanent-magnet magnetic levitation rail transit control system and method based on 5G communication technology. The system comprises: an intelligent control center, a 5G communication platform, a train security system, an Internet of things monitoring system, and a passenger service system. In the present invention, targeted at the problem of being difficult to ensure barrier-free transmission of signals even by means of beamforming technology due to high moving speed of a permanent-magnet magnetic levitation rail transit system and small coverage of 5G base stations, a multi-connectivity scheme is used, and the intelligent control center selects two 5G base stations for signal transmission at the same time depending on distribution of 5G base stations along a line, wherein one 5G base station is the current closest base station, and the other 5G base station is the next base station to be approached. By means of a relay-type base station passing mode, it is ensured that a 5G communication platform can provide a stable and reliable communication link.
