I feel like we could use an expansion for this route. Possibly add the Montclair Boonton Line or extend the line to Hackettstown. If it were to come with locomotives, I feel like adding the GP40PH-2b or PL42AC along with the Comet V would be a nice addition
Honestly, adding an unelectrified stretch with a new loco and a layer for the ALP45DP would be so worth it.
That can work extending it to Hackettstown although the rolling stock can be provided by this line RVL if made first they are the following that can be made gp40ph 2b 1991 built PL42AC 2006 built with comet IV-Vs
