I decided to look at the document in question and the first thing I found was:
The following persons were invited to participate in the Berkshire Flyer Working Group as
members:
Maurice O’Connell, CSX Transportation
Further discussion appears to suggest that Option 1A (or which is express service) would be simpler than Option B (construction of a wye in Schodack to bypass Albany) because Option B would require new negotiations with CSX for use of the additional trackage AND the construction of new signals to govern the new interchange.
Why I do find interesting BTW which I missed before is that the study does cover (at a very high level) the suggestion of a wye track built in Pittsfield at the location I suggested. It estimates the cost at $2-$5M but notes it would involve negotiations with CSX as well as the Housatonic Railroad Corp. (The image appears to also include storage tracks, but wye leg itself appears to avoid the wetlands. (page 60 btw)
Towards the end (page 134) Appendix E the study has CSX Passenger Train Access Principles. This appears to be a fairly generic and on-committal statement from CSX itself that has no specifics to this case.
So from the study itself, it appears that at least one CSX representative was involved, but beyond generic statements, there's no more details.
Again with a total of 2 trains a week planned, for 20 weeks a year, I think there's a greater chance than some here do.
