Terrific analysis. What is interesting to me is all of the items could be explained by a single factor: distributed planning architecture, such as a planning system that calculates each line frequency independently. Essentially each train is its own functional agent. This could cause the kind of data in the article, while also having a legitimate reason for use. Independent units can be better for fault tolerance, emergency recovery, and streamlined risk management, if anything goes awry.
