My reading of the above was that at the time of LZB going down, PZB could not be enforced immediately, because its assumptions were violated (multiple trains in the same zone). Hence the trains are stopped.
The question is then what does manual operation entail? Do they just continue operations, driving slowly and communicating through other channels while allowing PZB rules to continue to be violated, or do they have a protocol to re-establish PZB as quickly and safely as possible? Asking as a layman.
