Obviously you don't know either, Doctor.

And yes, it would be in the rule book
under headings for conductors and brakemen.

For the time period specified, I stand by
company paperwork I have.

I also insist that no matter how the wheels
were marked, those markings would have been
on the inside (back side) of the wheel, usually
on the rim or the hub or both and would have
required a person getting down and/or under
the car to check each wheel for markings,
stampings or cast-in markings.

An obvious exception would have been cars humped
in a yard where they had a car inspector sitting
in a pit equipped with bright lighting under and
between the rails, who was there to look for things
like missing or broken or out of place brake beams
or brake rigging, etc. He would have had a clear
view of the backside of each wheel.

Just as in the '70s when certain wheels were
banned and all cars had to be inspected and those
that passed inspection were marked with the yellow
circle on the black square (remember those), that
was solely a car department responsibilty, NOT
yard, train or engine crews.

Further, to clam that no freight trains traveled
over 35 or 40 mph ignores specific high speed freight
trains, marketed as such, on IC, C&O, NKP, NYC, SSW
and others.
