    ancient, authenticationless emergency train stop system was used by russia supporters in malicious way. you can tell it by fragments of russian anthem and putin speeches transmitted after the stop signal on the same frequency

    it’s three tones at a specific VHF frequency, it’s supposed to be transmitted by train and any other train in range has to stop automatically and immediately, but it’s close to 2m band so any baofeng can be used to transmit there

    it’s been a known issue for years and polish railways is migrating to GSM based, authenticated system, expected to be completed in two years

    How is it clickbait? The title is not sensationalized or misleading. It is a low-tech exploit of outdated radio control systems that has caused a lot of disruption for Poland.

      Low tech is a feature in safety systems though. Fewer dependancies and easier troubleshooting means better.
      We can't have nice things with Russia around though. I guess it's only a matter of time before they start spoofing TCAS or various radio navigation systems to cause civilian plane disruptions.
