Colorado's Winter Park Express put the Ski Train back in business, and that business is having a great run. Traveling between Denver and Winter Park Resort usually only on Saturdays and Sundays, the seasonal train service is often sold out. 

The Amtrak ski train is a revival of a historic train service between Denver and Winter Park to the northwest. The renewed service began Jan. 7, 2017, and is scheduled to continue through March 26. More than 15,000 people had ridden the ski train by Feb. 14, which was about the midpoint of its planned trips for the ski season. The train can carry 554 passengers. 

The original rail service connecting Denver and Winter Park, which sometimes is spelled Winterpark, started in 1912, and weekend journeys were added in 1940. In 2009, the service ended, partly because of financial reasons.
