Abstract (en)
[origin: EP0178158A2] A flaw detector for checking and continuously proving the integrity of railway tracks rails is given a second role to additionally sense markers attached to the rail webs. These markers, for example welded metal blocks, are arranged to reproduce a code word in the flaw sensor outputs representing the location of the vehicle. The code word is then transmitted, together with another code word representing the vehicle's identity, to a central traffic control office via a radio communication channel. The described arrangement may directly replace conventional track circuit apparatus.
