The Paris Metro has holding lights (3 white lights in a triangle) on or
near the headwall at many stations, used routinely to regulate the
service. In my experience LU have never tried to impose punctuality
controls in that way (except possibly on the ATO lines?).

Oh they do!

A red light until 30 secs before departure time seems to do the
business.

Yes, but isn't that just at termini and a few regulating points like
Hyde Park Corner? That still leaves stretches of a dozen or more
stations where no assistance is given to the drivers on accurate
timekeeping.
