Re: One reason Brightline has an engine on each end. But Amtrak is smarter than Brightline. As were WSDOT accountants
If the locomotives are reliable, for short regional-style passenger trains, you only need one. And a way to drive the train from the other end (cab car or
cabbage). When there's no cab car, push-pull needs either a locomotive on both ends or a cabbage on one end. Having 2 locomotives on a short train is expensive (locomotives cost more to run, even if just idling, than a cabbage).
If locomotives are NOT reliable, they need to be made so, or you need more than one per train, or you need a different locomotive. In any of those cases, they're costing too much money, and need to be fixed. The accountants are right. If the Chargers are breaking down too often, aren't they covered by a warranty? Siemens should be fixing them, and upgrading parts if any are not up to the task of daily operation.
Also remember: bookkeepers prepare the ingredients; accountants do the cooking; auditors try to figure out and write down the recipe. 🙄
