Agreed - Qantas and Ansett have 18 to 20 fights at 120 - 130 seats
between
them every day on the Adelaide Melbourne sector and never seem to have
too
much trouble filling them. (and if they do they have promotional fares)
The flying time is 70 minutes with a 20 minute check in at the
originating
end (90 minutes) and 15 or so minutes to collect your luggage (105
minutes)
but if you are travelling with cabin luggage only 90 minutes.
Add 15 minutes in Adelaide (20 in peak) to get from the city centre to
West Beach and you are back to 105 minutes. Add another 30 to 45
minutes
in Melbourne and you are looking at 135 to 155 minutes (2.25 to 2.5
hours)
If you apply the German maxim - "half as fast as flying" the transit
time
should be of the order of 4.5 to 5 hours which is not feasable with the
current track.
BUT - spend $100m and you cut 3 hours off the run (12.5 down to 9.5) -
spend
some more on the sharper curves in Victoria easing them slightly and you
could save another half hour (9 hours).
($80m regrade Mt Lofty to Murray Bridge and $20m resleepering in
Victoria)
Add a nice light fast railcar that tilts and increase the speed by only
10%
and you are looking at a transit time of a little over 8 hours.
Spend $300m on a new alignment Adelaide to Murray Bridge and $50m in
Victoria and the total time saving could be of the order of 4 hours
(8.5 hours) and with even a 10% increase in average speed over this
you get 7 hours 40 minutes.
Its all possible.
But the real saving here is the saving in freight transit times between
Adelaide and Melbourne and the possiblity of double stacking containers.
This should bring the freight costs between the two cities down
considerably.
