There is also the little issue of platforms that service multiple lines, a
situation that does not occur in Perth. A combination of very long trains,
curved platforms, people on the platform not boarding that train obstructing
the view.

Possibly - maybe all 6 and 8 car trains could pull up next to the display.
But, (just an idea - and extra money would have to be involved) with a 4 car
train, couldn't the driver stop, get out of his seat, open the doors, blow
the whistle, close the doors, see that they are all closed, then leave? If a
guard can work the train from the back of a 4 car train, couldn't the driver
do it from the front? It is just a thought, and would encounter some
resistance. There would also be increased dwell times at stations.

Don't they have 6 car trains during the peak on the Northern line? Or is
that something I read was proposed?
