A computer implemented method is for determining railway vehicle movement profile type of a railway vehicle movement profile. The railway vehicle movement profile includes a sequence of measured transmitted currents of a transceiver of a track circuit with respect to the time. The method includes obtaining a railway vehicle movement profile, normalizing the railway vehicle movement profile, extracting one or more features from the normalized railway vehicle movement profile, determining the distance of the extracted features with respect to each centroid of a railway vehicle movement profile type determined in a classification process, and assigning the railway vehicle movement profile to the railway vehicle movement profile type with the closest centroid

A set of stators of a linear induction motor are mounted on a track. A three-phase current is provided to each of the stators, such that a traveling magnetic field (TMF) is created by the stators along the length of the track. The traveling magnetic field includes a magnetic flux corresponding to a stator excitation modulated with a message signal. A rotor includes a series of conductor plates. As the traveling magnetic field passes through the conductor plates, a current is induced in the plates by induction. Such current then generates an opposing magnetic field causing the plates and the vehicle to be propelled. Each phase may first be modulated with a message signal, before being provided to the stator. The current at the rotor is then demodulated to realize the message signal. A doppler shift due to the speed of the rotor relative to the stator is corrected.

Example inductive loop detection systems and methods are described. In one implementation, a method receives image data from a camera of a vehicle and determines a geographic position of the vehicle. Based on the image data and the geographic position of the vehicle, the method determines a location of an inductive loop in a roadway proximate the vehicle. The data associated with the location of the inductive loop is stored in a storage device within the vehicle. For a vehicle, a detectable zone may be determined based on actual or simulated outputs an inductive loop system at various locations relative to the vehicle. While driving, the vehicle is controlled to cause the detectable zone to pass over or stop over a known location of the inductive loop.

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.
