This locomotive is designed to have an HEP system that is isolated from the main engine. It's top design speed, like other Genesis models, is 110mph. It's only seen on the Albany-NYC corridor because it's a dual-mode locomotive. It's unique because it has third-rail pickup shoes, which can pick up electric current instead of having the onboard engines producing. This is only used for entry into NYC Penn Station. The engines are shut off and it uses solely third-rail power due to the emissions ban instituted back in the 1900's. The reason why you don't see it around outside of the ALB-NYC area is due to it being specifically designed for this route. These locomotives aren't needed anywhere else.
Thanks for the explaination, Don! But one thing puzzles me. They continue west past Albany. Not sure how far west, but I think at least as far as Syracuse.
That might be due to there being no P42DC's available at the time. I'm just assuming, but I think Amtrak is strapped for power right now. So many of their P42DC's have had to be loaned to CALTRANS and MDOT for their corridor trains that they have to use the older P32-8BWH loco's on the cross-country trains. Normally the power swap is at Rensselaer. The F59PHI's are starting to reach their age, so are the Genesis series. I do hope Amtrak can get some new diesel power soon, otherwise it won't be pretty.
Something I've also been curious about is why the Chicago facility allows the specially modified P42DC's (for GE ITCS and DPU technology) for the higher speed trains leave and go all the way out west. There is no point, they're useless there in that configuration. And instead the trains that need the DPU configurations have to put both loco's up front awkwardly. Perhaps they didn't recognize those locomotives were modified and did it by mistake. In that case Amtrak needs to do like CSX does and put a lightning strike symbol or something on them to prevent it from happening. I've also seen that #64 was out here (the East Coast, A-Line) a few days back. That locomotive shouldn't be out here, it should be in Michigan and Illinois.
This is what I'm talking about. You can tell the difference b/c they have a rectangular 'box' on the roof above the conductors side. The regular P42DC's don't.
