Abstract (en)
[origin: EP1741612A2] The method involves using a controller (4) to evaluate the absorption and change in the resonant frequency of a resonant circuit when driving a rail vehicle (12) on a section of a rail track (1). The resonant frequency is provided in the section of the rail track. The rail vehicle sends a pulsed signal to the controller to set the threshold or temporal behavior of the controller in busy condition based on the change in resonant frequency of the resonant circuit. Independent claims are included for the following: (1) Arrangement for monitoring switch rail or rail track area for rail vehicle; (2) Rail vehicle; and (3) Monitoring device.
