Why diesel for motive power and electric third rail for the rest if you're concerned about emissions? Why not electric all over the place? Can't they run catenary all the way up?
Of course, there's one problem with the Empire service: the swing bridge north of Penn. But you may be able to get away with it if there's a battery system on it.
