Get real - in Sydney, we are talking about drivers cabs on half the fleet -
that is over 1000 cabs. We are also talking about cameras at every station -
all 300 of them? Then there is the problem of interference between
platforms - what if you have a situation like North Sydney, platform 2 and
3, with both trains leaving in the up direction, so the transmitters would
bahe to be at the Sydney end of the platfrom for both platforms. The chances
of a train picking up an erroneous signal are too great. (I know, it SHOULD
be apparent to the driver that he or she is looking at the wrong side, but
we cannot rely on that).
