Second rate Alice - Darwin line?

[dbromage@fang.omni.com.au (David Bromage)]

The Australian (29/10, p1) reports that 155,000t of rail will be required
to build the 1410km line. Leaving aside sigings for a moment, the main
line alone requires 1,410,000 * 2 * 60 = 169,200 t of rail.

Let's add 10 loops at 1.6km each, plus another 80km for 5 sidings. This
gives 3.3 million metres of rail.

Here's the punchline: 155,000,000 kg / 3,300,000 m = 46.96 kg/m.

Can they relly be so stupid as to build it with 47kg rail??????

Cheers
