I'm not sure, I can follow you. The trains were in LZB mode, because you need that in order to operate a high-speed train. You can't see the signals required for PZB at high-speeds.

The trains did stop when the LZB reported an error, like they should.
> follow some different protocol
That is manual operation, which I suspect they failed to do.
