The chances of any abandoned railroads coming back are always next to nothing... especially in the public sector. I'd say if they were making a decision on which route to keep today, they would probably have kept the ex-main Line instead of the Graham since most traffic is now passenger and that line travels through more densely populated areas. It's probably fewer miles to Port Jervis as well but I don't have the exact numbers.
I think it may be possible that NJ Transit might not be the perfect, infallible organization that most people assume it is.
