I'm not sure that Moncton- Matapedia is all that scenic, other than the Matapedia valley which happens before breakfast and in dark for part of the year.
The bigger problem is the scarcity of sidings on the Napadogan route and the potential for CN to give priority to freight.
The Ocean operates on a shoestring, and its survival depends on politics. Those towns along the Matapedia route do provide some business. It's a bit of Northlander 2.0 Perhaps some investment in a Matapedia-Moncton-Halifax day train is possible, although past studies haven't supported this idea. The Trans Canada Highway thru that stretch has had some nasty tragedies and a non highway travel option might be more popular than is imagined. And, the route is increasingly economically challenged. Possibly Sudbury-SSM is a valid comparator. Rail service is a nice fantasy but the cost envelope may not be realistic.
The number of track switches thru New Brunswick is small, and speeds aren't that much higher than the restriction. The potential for harm is not the same as in the corridor. So while the risk is there, perhaps moving off this route and/or signalling it is overthinking. It remains to be seen whether maintaining the Ocean beyond end of life for the current equipment is really a priority..... we have submarines and fighter jets to pay for, and the national budget can't afford everything. I'm not optimistic.
