Ok, I'm trying to wrap my head around the external power tender. It's bypassing the prime movers, and applying power directly to the traction motors. So, how do the controls work? Since the "notches" are virtual, does the software detect that external power is applied, and just operate the locomotive like a sprinter? That means that the transformer/rectifier/solid state converter that is connected to the pantograph is effectively part of the locomotive, much like the battery pack. Do we know if power is transmitted through the train, like MU controls, so it's distributed to the rear locomotive?
I've said it before, The run through shouldn't be just a conventional MARC consist runthrough, it should be EMU/BMU that's shared between MARC and VRE, which can operate almost as a "metro Express" when going through DC proper.
Basically. It'll work like a Sprinter. I doubt there's a "rear locomotive" in this case and it's more like cab controls at the rear end, so it's push-pull operation. Basically MARC or the Keystones but "backwards" looks better than the butt end of a coach.
That said... yes, I can see an express service, Alexandria/King Street to New Carollton with Crystal City, L'Efant Plaza, and DC Union Station being the stops. I can see that being dual-mode electric/diesel or electric/battery until it's electrified.
Electrify all the way down to North Carolina? Eventually.
