The 489 obsession

Not to mention the 657, which is the precursor to the 741. Yep, the same 657 responsible for all those neutral drops from the push button automatic max wedge cars. And, say what you will, but the keywayed drums of the early cars were a pretty stout unit as well. Of course, most passenger cars were so crusty that you needed a drum puller to get them off. But if you can survive several hundred neutral drops, I’d say it’s a good unto.
