an argument against pushing lightly loaded trains around corners.

I like the way the operator of the snow sweeper just gets on with his job
and doesn’t stop to film it Social media .Perhaps that is because that that
junction seems to have quite a few incidents . Only a few weeks ago the
same camera picked up a car whose truck(bogie) had become detached from the
pivot and was running loose further back under the car.

It's an extremely tight reverse curve as part of a complex more than
4-way junction next to the Kansas River, in Kansas City. KS. The
bridge continues over the river as the upper deck of a double decker
bridge,

They're always having trouble on this curve. The bowstring effect of
80' cars doesn't help.

It's a great place to watch trains, and there's always someone with a
camerta as well as the fixed cameras.

I find it odd how US railway vehicles don't have their bogies (or even it
seems the axles) attached in any meaningful way other than via gravity meaning
during a derailment they fly off all over the place which aside from meaning
more work during clearup but the potential for killing someone nearby.

Not just the US. See

The coaches were not fitted with any form of bogie retention in the
vertical direction, and this allowed the vehicle bodies to lift off their
bogies during the derailment. As a consequence of losing their bogies,
three of the coaches were free to slide and roll in an uncontrolled manner
(attached bogies tend
to resist sliding because they dig into the ballast). The detached bogies
also became obstacles in the path of the vehicle bodies, and the second
coach probably suffered penetration damage as a result of striking detached
bogies.

Ouch. One has to wonder at the thought processes behind the engineer who
decided against a bogie retention system. Hopefully its not the case with
modern UK stock.
