Nice model Olof, I enjoyed the working features and the colour scheme is
fantastic, very industrial looking.

This prototype, if I read the info right, has like half that HP... Denmark is
not completely flat by any means, either. Lots of gear jamming there I bet.

I think the prototype has 520HP, which is pretty good going. They generally say
that 10HP per ton is a good power to weight ratio.

One thing that I didn’t comment on before is the rather (to my view) bizarre
axle arrangement. Most US trucks have one steered axle and if they are 3
axles, 2 powered or one powered and one idler. The thought of having 2 out of
3 axles steered and only one powered is strange. It seems to not be needed
for US road clearances where wide turning circles are possible.
Is this a common european arrangement, to have two steered axles? Why even
HAVE 3 axles? For weight per axle limits?

This is a common arrangement here in the UK, the tractor has to have three axles
to allow the maximum gross vehicle weight of 44 tons. Sometimes the second
(idler) axle is steered, which saves on tire wear - remember that the wheelbase
of these trucks is much smaller than their US equivalents, so tire wear when
cornering will be more severe. The second axle is not steered in all tractors
though; the advantage of having it not steered is that steering linkages travel
alongside the chassis of truck, so avoiding them frees up space for additional
fuel tanks, tool boxes, etc.
It is extremely rare for a truck to have more than one driven axle here - in
fact the only time you see this is if a truck is frequently used off road, such
as tippers. I suspect this is partly due to economic factors, as extra driven
axles mean additional deadweight and fuel consumption; the latter is of
particular relevance in the UK since fuel prices are extremely high compared
with the US.
