Re: Freight Car Distribution on smaller RRs

While the Nelson-Gilbert study is a valuable tool it does not apply in every instance.Regional carriers will get more traffic from railroads that either directly connect or are in close proximity.After carefully studying wheel reports for several years I must conclude that what I possess is a better indicator of what ran on the roads that I model.Company annual reports also support my findings.Armand Premo

Al, it's not how you are "biased," but how box car supply works.
The Nelson-Gilbert theory provides a convincing if not fine-grained
description of it. And it's not about "bias."
