Northern Tier Passenger Rail Study final report was published last week: https://www.mass.gov/doc/northern-tier-passenger-rail-study-final-report/download
Not surprisingly, they punted on any serious recommendations by concluding that more study was needed about travel demand on the corridor (translation: they couldn't find hardly any west of Commuter Rail territory). They did mention in passing evaluating better coach bus service on the corridor as a route priming strategy...but it was literally only one sentence so not all that clear they're giving it serious thought.
How much money goes down the drain in studies like this where the outcome is pre-ordained? Not asking rhetorically - would we know?
