The contactless express train-control mutual position of rails of the railway track

In article the device of the control of linear vertical, linear cross-section horizontal and angular movings, and also width of top of a head of a rail is considered. Matrix configuration and inphase excitation eddy current the converters is offered, allowing to create the common electromagnetic field providing the control over a wide range of change of geometrical parameters. The technique of recognition of an electromagnetic image of a rail is based on selection of controllable factors by means of digital processing measuring signals.
