South of the freight main line, there's actually nothing there. No path, no nothing. The old l&l right of way is "gone".  If you were to try to follow it you'd just be bushwhacking through woods.  The tunnel under the freight line is filled in with landfill. It's probably best to leave that either as the abandoned railway or as nothing. The paths north of that I've surveyed with gps - I know the area quite well.  Cheers!
