This still does not address the curved platform issue, or the fact that
because we run 8 car trains here, the driver cannot just use one camera to
view the whole platform, even on straight platforms in some situations.

How can the driver *reliably* view multiple camera inputs on a single
screen at the same time unless the screen is platform-mounted and large
(which requires the train to pull up at the same spot all the time,
regardless of length), or the in-cab display takes up a very large slab on
the in-cab space.

Perth trains are very short (no longer than 4 cars), so there's a
fundamental problem saying that what Perth does can be directly translated
to Sydney and it'll work like a charm.

The fundamental issues are still being ignored by everyone as though they
don't exist. 8-)
