I've been a bit slow on the draw, but I expect to pull the trigger on a Charger in Amtrak and one in Metro-North this year.
It's a bit of a dilemma, I could see situations where a future Amtrak consist would rate doubled-up Chargers, but the thought of having three $800-ish locos coming due in one shot is a trifle intimidating on an order of magnitude greater than those five Viewliners I bought (I 'm in the habit of paying off my plastic in full every month). I have plenty of Genesis locos, but those are of course all DCS, so no MU-ing any of those with a Charger other than a "stunt" consist, where I run the train with two remotes. So far as Metro-North, this would be my only (?) chance at getting a current-era Metro-North unit around the time they're taking delivery of their Chargers, and since no prototypical M-N consist rates double-headed power, their being TMCC isn't an issue.
Sure makes a lot of sense to me! A commuter charger seems relatively future proof and a Phase 7 Amtrak Charger will perhaps look nice running alone with an Airo set one day.
