I wasn't too impressed with the article. The author seems to be focusing on the evil devil "Gardner" as the source of all of Amtrak's problems. But we all know that the problem with the evil devil "Gardner" is that he supports corridor service over long-distance service, especially, "experiential" long distance service on the secondary long-distance trains. And that the evil devil Gardner has some sort of secret agenda to kill the long-distance trains, only being restrained from doing so by Congress. But the most recent insult to Amtrak service is that state-funded Wolverine trains have been cancelled! Why would the evil devil Gardner want to do that? The state of Michigan is paying for the trains. Does the evil devil Gardner hate Michigan or something? It doesn't make sense.
In the real world, there are a lot more people in management than Gardner who have made some bad decisions, although it's not clear that at the time they made the decision, it was such a bad idea, or else, the bad decision was the least bad of all of the possible decisions. Or that other people beside Gardner just screwed up, and Gardner was trying to avoid being a micro-manager, which is something that I, being the recipient of micromanaging during my career, appreciate. Or it may be beyond Gardner and specific Amtrak managers, but rather a general belief among the managerial class in this country that employees that don't require a college education are abundant and fungible, and thus can be treated like dirt. Given that these problems are found in more companies and industries than Amtrak and passenger rail, that does seem likely.
That said, I agree that Amtrak has a lot of problems right now. But getting rid of Garner won't solve them.
