Umm, six slots is three takeoffs and three landings, at present there are
often seven or eight flights per hour in each direction between SYD and MEL
(mainly in the peaks though) and reducing this to three or four per hour
achieves the six per hour reduction in movements that David mentioned.

Also, why would the international flights still have to fly the SYD to MEL
sector? Plenty of international carriers only serve one of these ports, and
it would be an easy matter for the train to be brought into the airline CRS,
effectively meaning through ticketing and fares - as the proposal is to run
it via YSSY anyway (YSSY is SYD airport) it would be quite an easy matter to
ticket someone from MEL to YSSY on the VHST and YSSY to wherever on
whichever airline they were flying on.
