No, the guard or platform dispatcher steps back from the train when they dispatch so has a clear view of the whole train.
Hmm... pretty sure they can't do that on a large number of platforms due to platform curvature, seems like you'd need at least two people, maybe three. Doesn't strike me as a foolproof solution.
Basically it's a technology problem, the doors didn't close properly. The solution should really be a safer door design with backup controls. If a system is fallible, the foolproof solution is not necessarily a human (who is also fallible)
