The New England Southern Railroad. (And a little bit of PAR and Winnipesaukee scenic rr)

The New England southern railroad is a short line (I love short lines, can't ya tell?) in mid-New Hampshire. It's sole interchange point is with Pan Am railways in Concord (I think?) They mainly haul construction materials, grain, salt and LP gas. They also serve a Slurry plant in Tilton, NH monthly.
A couple of questions, though, for those who can answer.
1. Does anyone know where the Slurry plant actually is? I haven't been able to find it. (EDIT: Found it, never mind)
2. I'm debating with myself if I should stop the route at either Laconia or Meridith. Tell me what you think.
3. Where can I find other industries located along the line? Can't model a route without knowing the details.
Little bit of description of the scenery. Woods, more woods, causeways, swamps, Interstate 93, city area of Concord, Lake Winnipesaukee. Get it? Got it? Good.
