It's sick that emitting radio waves is punishable by law.
If your system is vulnerable to that, it's your problem. Secure it better.
It's not them who stopped the trains. It's their system that did, by picking up a signal it shouldn't have picked up.

I guess you don't like having a reliable mobile phone service and undisturbed wifi at home.

The Polish radiostop system is completely unsecured, so it is rather bad example to have this discussion. But in general, when it comes to radio, it is unfortunately not as simple as "secure it better". Sure, you can use spread spectrum, CDMA and whatever else is there when it comes to radio, cryptography and information theory techniques but all of this goes down the drain if you just use strong enough jammer emitting carrier on top of your desired signal.

Most countries have radio wave regulation. If you don't believe it, you can try to transmit radio signals in the restricted frequency band.
