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.

IIRC, there is a countdown clock at Paris Metro termini and a horn
sounds when it is time to depart.

On some lines in Paris, a horn sounds in the driver's cab at every
station when it is time to depart. On some other lines, there is a
headwall digital clock that is set X minutes slow, where X is the
timetabled running time to that station from the start of the line.
Thus the correct time to depart always has the same displayed time at
each station.
