All they have to do is restart the old passenger rail system they had in the 40s. It connected the entire front range with salt lake and all the major cities in utah including park city, went down to santa fe in the south, and hit just about all the towns and ski resorts that were around at the time. Even the ones that are a little more annoying to get to today like aspen or telluride.

What is even more tempting is that all this infrastructure and right of ways are still there. A lot of these towns have the old station land empty still, some have the old station preserved even. A lot of the rail grades are either sustained by freight rail or have been railbanked as trails. Its practically turn key as the hard part of gathering all this land was done over a century ago.

Too bad rail ambition is so paltry in comparison today.
