Gene--

IMHO, there is no one STMFC distribution model that can be universally
applied by all STMFC modellers. Each has its own merits. But it's
said that when the only tool that one has is a hammer, every problem
becomes a nail.

STMFC layout owners could use primary sources (i.e. switch lists,
wheel reports) for car distribution--if they were available. Of
course, for most this is not the case. But to rely on any one model
alone is fraught with peril. I like the N-G (seems to be mostly
overhead traffic on a transcon piece of the UPRR) data, but can I
really use it in MY STMFC layout roster? I'm more inclined to
consider (and favour the study of to determine my STMFC roster) what
was shipped/received/overhead traffic in my prototype line segment.

And this discussion makes me realise that those GA, D&H, and B&M
boxcars are not going to be seen on my 1956 Eastern Ontario layout too
often!
