for now, the Montclair & Boonton Lines and the Morris & Essex lines will be the ones that the locomotives do runs on. Once there territory is expanded, I would think North Jersey Coast Line would be the next best candidate. After that, we would have to wait for the powers that be to give the all go for revenue service into Penn Station before we see any major changes in where they are put into service. I also heard that the Port Jervis line may be receiving a few since the dual modes are slated to replace NJT's F40PH-2CATs, a lot of which run up that way from Hoboken.
