The trains have no drivers. They are ‘robot trains’ (according to a little girl staying in the same apartment block as us).
Which probably goes a long way to explaining why they run so efficiently – no pesky unionised drivers to go on strike.
It also explains why it’s so easy for family groups to get separated boarding the trains – no drivers to check that everybody is on.

Robot trains sound cool….. Losing 1 of the girls not so much!! xxpt
That is a bit scary! Have you got a safety routine worked out for separations. Are there any pesky human workers on the platforms?
I believe that there are drivers, but they’re just there “in case”, and don’t actually HAVE to drive the trains if they don’t want.
(This is assuming that “trains” = MRTs.)
