You're talking about getting people into the mountains without cars and buses, not moving people between separate resorts. People who want to ski all three Wasatch areas either stay in SLC and drive to the resorts--I think trains would be an excellent although extremely expensive way to move those people--or book a couple of days in all three areas. I doubt most people who want to ski all three areas are going to stay in one ski location and ride lifts to the other, given the time it would take out of their ski day, especially on powder days when snow safety will take hours (and much more terrain to control). (Also--snow safety on the south facing slopes in the canyon which is currently done with guns and remote devices to protect the roads will now have to be done by hand in addition to protect skiers). There is also the problem of lifts going over high ridges and passes closing in bad weather.
Just to put a bit of perspective on this comment, One Wasatch is modeled after European resorts, where in fact you get up into the mountains and simply stay there, no car needed. I'm encouraged to have seen about 30 people getting on the bus at a local Park City hotel yesterday, the Park City bus system is pretty darn good at getting people to and from the hill. The Park and Ride lots at the base of the Cottonwoods are pretty efficient as well. But from a visitor standpoint -or locals- I maintain that the three lifts necessary to connect the Wasatch resorts will be an environmental net gain. Consider the statement quoted above, then consider the world's largest ski area, The Three Vallees:
When staying there, you simply ski back and forth to whatever area you're interested in for the day, then ski back to your lodging or house. There are many dozens of areas like this in Europe, and it's a fantastic to experience, dare I say cool? I was dropped off at the Three Valleys for a week, I never even thought of needing a car. Yes, One could live or stay in Park City, Big Cottonwood, or Little Cottonwood for a week and not need a car as well, yet get to explore all of the different areas. The Three Valleys is more than three times as big as One Wasatch is proposed to be, I've had many memorable days of skiing from one side to the other with lot's of pow runs in between. The Valley on the left side of this map -Courchevel- is Park City's sister city. There's a run there named Park City, and a run at Park City named Courchevel. The two towns do annual student exchanges, dignitary visits, etc.
