I was looking at some maps, and I was thinking these locomotives would be perfect for secondary "old road" routes that spend a lot of time in electrified terminal areas, such as DC, Boston, Harrisburg, and I'm not sure if the lines are still up out west from the Milwaukee road, but you could theoretically utilize the old overhead scheme, even if new wires need to go up, from near the lakes before you cross the northern plains. I think there may be tunnels or avalanche shields out there that may not be suitable for overhead lines, in which case in the longer tunnels you could utilize overhead rail. But that's an Amtrak thing, not nj transit.
As far as nj transit uses, also dis some reading up and looking at maps. I feel these locomotives have the potential, over time, to restore quite a bit of former passenger service in nj especially central and southern. You could end up with a statewide rail network verses a new York and Hoboken centric system. Sure, the current lines, extended a bit or not, would stay pretty unhchanged, but I mean, I think there's a market for both summer beach service, and cape may area service. It would help keep jobs in the state, allow families to be closer (if they want), and it would un-clog tue turnpike of intra-state traffic.
No I'm not a railroad professional, but that doesn't mean I can't provide first hand observational comments.
