Both lines, of course, rely on a driver in the cab to control the
on-board systems, so they are not completely automatic.
In Paris, Line 14 of the Métro has no staff on trains or, as far as I
could see, on platforms. Even at the terminus, if you fail to alight,
they take you into the reversing siding for a few minutes before
starting the return journey.

That sounds to me very unsafe, in the event of an emergency like what
we had here recently, evecuation would have been much slower, plus some
stations need to have different 'dwell times.'
