The Milan Metro is one of the nosiest I've ever traveled on. Regular
users would end up with hearing loss if they don't wear 'protection'. It
was bad. Although the train control system has nothing to do with that,
the noise is bad civil engineering.

I've been riding at the front of a DLR train when a car attendant came
up and ask could I move. They opened the panel and manually bough the
train to a stop at the next station and manually started it again.
Apparently building works at the station caused them to temporary move
the stopping points and it was easier to have the staff override the
approach than to alter the automation. UK law requires a 'qualified
person' on board, so every service has a staff member on board, just not
up the front.

I've also been on a Singapore Circle train on Sunday morning to find I
couldn't get up the front. They use Sunday mornings for the staff to get
practice at 'coded manual' operation of service trains. Sydney Metro
regularly rosters staff on 'training runs' but they do it with empty
trains in the non service hours.

Train automation is a given. It's only a matter of time before even
Sydney's big 'deckers' get automated. Street running trams will only be
a short ways behind - the automation will need a degree of
aggressiveness to force its way through pedestrians :-)
