The real interesting thing about the BSPRA wanting a study for the North Coast Hiawatha is that they already commissioned one earlier this year, performed by the Rail Passengers Association:

This study, which they unequivocally stand behind (their words), actually shows that a restored North Coast Hiawatha would have little utility in North Dakota and Montana. While constantly harping that such a train would serve more population centers in those states than the Empire Builder, their own study shows that in pre-Covid FY2019, ridership on the Empire Builder in North Dakota and Montana was 8,276 and 1,720 greater respectively than would be achieved by a North Coast Hiawatha. The study also shows that while North Dakota and Montana have 49% of the route mileage, the two states would produce only 24% of the ridership. Fargo/Moorhead has a metro population about twice that of Bismarck/Mandan, but ridership at the later would be twice that of the former. Sandpoint, Idaho would have much greater ridership than Spokane, and the Tri-Cities would have greater ridership than Seattle. And most amazingly, Bozeman – the stop for Yellowstone National Park, the Big Sky Resort, and Montana’s largest university with by far the largest number of airline boardings in the state because of those factors – would have an annual ridership only 86% that of East Glacier Park along the Empire Builder route, a stop that is only open five months of the year. The study makes no accommodation for tourism or pretty much anything else, it’s all about cherrypicked county population and uniform applied percentages. And the study does not take into account any of these mandatory parameters: Train schedule, station infrastructure, station amenities, additional track infrastructure, crew districts, or infrastructure for mechanical and train inspection requirements.
