TB added:
They might get away with less than 36t axle load and
use updated "wheel slip" tech, but even that has its
limitations. Its a lot of power, and some of it will
be wasted if they do not get the adhesion factor right,
and you can not beat mass for that.!
I found the BHP press release interesting, they say the
present 240 car trains have four Loco's, (unless that
was a typo) the last time I was over in the Pilbara
(1989) they were using five locos, perhaps Dash-8
technology played a part there.
