It's barebones enough that it makes me wish I was actually in the room to hear what he said
It's definitely a presentation designed to accompany a voice-over or in-person discussion.
What does a Bottling plant closing in Mass have to do with running freight on the Mountain Division?
Without being there to actually hear the discussion, it's hard to tell. That said, based on the slides highlighting missing rail access at the Northampton facility, and such a plant's need for clean water, I'm guessing that his case was that rail access plus Maine's natural resources can bring jobs and money to the area potentially served by the Mountain Division.
In any case, it's certainly nothing definite and probably not worth spending $$$ on without firm commits and/or contributions from shippers. I see trail use as inevitable and the real battle should be how to build this as a rail-with-trail since the odds of a trail being removed to replace rail are probably less than winning the lottery.
