and he notes -
The only practice I can recall for freight car placement in a train
was the use of a box car behind the tender when the train was a solid
string of tank cars. This was (also if I recall) due to tracking problems.
For the most part, cars were spotted in a freight train according to
their destination and were 'blocked' by yard crews accordingly.
Empties, (even flat cars) were heavy enough to track properly and I
see them in videos just about anywhere in the train.Exceptionally
heavy loads were usually dispatched in special trains with idler cars
separating them for bridge restrictions.
On a model railroad, brass or other heavily weighted cars may pose a
problem if the lighter cars are spotted ahead of them but that's not
a prototypical dilemma.
