I think that all of the rail around CP Sterling has been replaced within the past couple years... in fact I think all the rail to at least Harriman is relatively new. West of there, I'm not sure if there is any stick rail left on the Main. What switch is at Arden? Is there a freight siding there?
I think it may be possible that NJ Transit might not be the perfect, infallible organization that most people assume it is.
