Here's a new phenomenon: carrying out Underground track repairs
whilst a train is in service, which is deliberately held up for that

No nothing new, it's been happening for several decades.


What would have happened had a serious fault been found, i.e. one that
meant
the train would not have been able to proceed further?

The procedure "staff working in double track tunnels" wouldn't have been
introduced if it was suspected to be a fault that would require a suspension
of service.

And, aren't there health and safety rules about "track possessions" and
switching off the current before workers start fumbling about in
semi-darkness?

Hence the train protecting them. Under the electricity at work act 1989,
current should be discharged unless there is a good reason not to do so.
Perhaps the work they were doing require current to be on to identify /
remedy the fault?
