And even if it was allowed, there is no guarantee that an authorized person would tune in to a camera of a given train in time to see somebody nodded off at the controls, and even if there were... there is nothing they could do to stop a train, short of calling the proper train dispatcher to drop the next interlocking signal on them and letting PTC (once active) stop the train if an unanswered alertor has not done so already. And there is no guarantee that something tragic would not have already happened, like rear-ending a train ahead in the next automatic block (in non-cab signal territory, which PTC would not prevent, since the preceding intermediate/automatic signal would be a Restricting aspect, and not a Stop Signal).
The recent head-on of two CSX trains in Florida is proof yet again that while two sets of eyes in the cab can be better, it does not always prevent tragedy. The engineer has admitted to investigators to falling asleep before the collision. Granted that is information that was likely not supposed to be released to the press, but nevertheless it is now out there. And that now brings up the question of why did the conductor not observe the situation and pull the emergency brake on his side before the stop signal?
So many what-ifs, and answers that are yet to come...
