A train is a horizontal lift that runs to a timetable. The timetable

I was reading an article about Barcelona's new driverless (and mostly
service-less) lines 9 and 10... Some of the stations are very deep,
and can only have lifts, and it's claimed that these (will) have an
interface with the central system in order to control passenger flows
through the station. If actually done this way, I suppose they would
be vertical lifts that run to a timetable.

So, if places like Italy, France, Spain and Denmark are building lines
with crewless trains, or even converting existing lines, if the DLR runs
without any difficulties without either a driver or PEDs, if the
Canadians and Merkins can operate Sky Train-type services, then why all
the potential difficulty here in London?
