The problem I see with a SSM-NB service is I don't think there is the potential ridership (I say that not really knowing any numbers - perhaps some bus numbers would be instructive). When you think of nodes, there is not a lot of connection between SMM, Sudbury and NB. They are each centres for their own catchment area but I'm not sure there is a lot of intercity dynamic. They each have air service, good sized health centres, adequate shopping, etc. and their isn't a lot of population along the line. The track would also need significant work to allow reasonable passenger speeds..
I'm not sure what current travel numbers are, but the case for such a service would be this:
1) University. Yes, each Of these three communities, SSM, Sudbury and NB all have them. But Sudbury's is by far the largest and most comprehensive.
Compare the student body at 9,000 and change for Laurentian (Sudbury) to less than 2,000 at Algoma (SSM).
2) Healthcare, SSM has a brand spanking new hospital, but at 289 bed, its a bit over 1/2 the size of Health Science North, which as of next month or so will be only one of these three to have a PET scanner (when it becomes the first in the near-north to have one.
3)Connection to Toronto; any rail connections to Toronto are going to be routed from Sudbury, or NB or both. I don't see any direct connection for SSM; so the connection to these other locations becomes important as they act as transportation hubs for SSM.
That said, I'm not suggesting this is the big priority in terms of a rail investment; but I do support the route (if only by bus) and that it be carefully considered for rail.
