The Zephyr continues on to SLC and Truckee but I'm not familiar with the stations' proximity to the slopes in those locals.
I know I'm bumping an old thread, but I've done this a few times and can comment.
The Zephyr is fairly popular for skiers. However, as mentioned, it is often late into Denver (as well as the other direction), and frequently gets more late headed into the mountains where it often has to wait hours sitting in the hole at sidings for slow freights to trundle by. Basically, don't plan on skiing the day you get off in WP- if you get there early, great.
Also note that Fraser is several miles up the road, and the bus will take time to get there.
As somebody mentioned below, Glenwood Springs, and Sunlight make an excellent stop- I've done this a few times. You get amazing scenery for the ride up, Glenwood is well served by buses, and the ski area has a shuttle that makes the hotel rounds. The ski swim and stay package gets you lodging, lift tickets, and hot springs pool tickets (Glenwood has the largest Hot Springs Pool in the world, and it is WONDERFUL after a day of skiing) that are ridiculously cheap.
