To QB's point, PAR's issues are only one factor related to a MMA's health- and a relatively minor one, at that. Keep in mind that the old CP line is MMA's preferred routing. And even prior to the line being sold by CP, BAR historically played off CP and MEC/BM against each other to their benefit.
I don't think one tear would be shed if PAR was to sell out. It's doubtful that a Class 1 would buy in, though... not enough traffic potential. Consider this "what-if" scenario: Remaining PAR system east of Ayer is sold to Railworld and merged with MMA operation. First, look at history: The MEC kept the Mountain sub open for its revenue advantage vs routing freight over BM. As that advantage disappeared when MEC and BM came under common ownership, one of the first things Guilford did was shutter the Mountain Sub. So, flash forward to the MMA scenario. The CP line shares the same characteristics as the Mountain sub: An underutilized overhead route with no substantial on-line business, operating in a region that has alternative routes. What would you think MMA would do?
