Here's a new phenomenon: carrying out Underground track repairs

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?

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

There are rules about possessions, but it is not necessary to have a
possession for work to be carried out. Where the track is concerned the only
thing likely to stop a train proceeding is a section of rail missing. If
some other problem arises then there are rules that the driver must follow
to get round the problem and keep trains moving, even if at reduced speed
and/or frequency.
