(erielack) Riding the Commuter Lines

[Ken <lackawanna_@_iname.com>]

It's been nearly 30 years since I left NJ, and things have changed.  Wonder 
if any can answer some questions:
Mileposts north of Suffern sometimes are identified "JS" or something other 
than JC, but the mile number remains the same.  What do these initials mean?

If I recall correctly, NS/Metro-North abandoned commuter service on the old 
Main Line and now runs everything via the freight cutoff.  I looked for 
where the old main and cutoff might meet, but couldn't find any evidence of 
the junctions.  Where were they, and what still exists?

Does the east-west track from Suffern still connect to the NJ&NY/Pascack 
Valley line?

I'll have more questions--when I remember them!

Thanks.

Ken B.
