Nuremberg, Germany here. http://en.wikipedia.org/wiki/Nuremberg_U-Bahn#ATC_and_driverless_trains http://en.wikipedia.org/wiki/Nuremberg_U-Bahn#ATC_and_driver... We have driverless trains without drivers at all. There is some staff getting into random trains to check for problems (like problematic passengers, etc). Interesting thing: the migration is going gradually, there are trains with drivers running on the same line than driverless trains, and IIRC this was never done before.
