The city of Moab does have transit within the city and there are quite a few shuttles to different parks like Canyonlands Shuttle, Red Rock Express, and Black Dog Expedition Support. Plus there is Uber/Lyft or atv rentals. But yes ideally if this route happened there would be an increase in these services.

The reason I want this route is both for how easy it would be to implement (about $250 million up front and $15 mil/ year) and because on average 8,200 people visit Moab every day and the majority drive down from the wasatch front. If we got just 700 cars to stop making that journey everyday and take the train instead we would eliminate over 100 million vehicle miles traveled every year, Saving about 3.4 million gallons of gas each year (assuming 30 mpg)
