Amtrak has added a second Ski Train trip from Denver to Winter Park Resort later this month after overwhelming demand for what was originally planned as a one-time-only revival.

All 400 tickets for the first trip — created as part of the ski area’s 75th anniversary — on March 14 sold out in 10 hours. The second trip will run the next day, March 15, Amtrak announced on Tuesday.

Each round-trip adult fare will cost $75 and passengers will receive a $15 gift voucher for use at resort restaurants and retail stores. Discounted lift tickets are also available by calling the resort in advance.

The train leaves Denver’s Union Station at 7 a.m. and arrives at the resort at 9 a.m. It then leaves Winter Park at 4:15 p.m.to return to Denver at 6:15 p.m.

Beginning in 1940, the Ski Train carried skiers between Denver and Winter Park every ski season through 2009. The operation lost money, and investor Philip Anschutz, who acquired the Ski Train in 1988, sold the business in 2009, citing the rising cost of insurance coverage, declining profits and operating issues with freight trains on the line.

The 56-mile route — which reaches Winter Park’s slopes via the 6.2-mile Moffat Tunnel beneath the Continental Divide — played a vital role in establishing the Denver-owned ski area.

“The strong customer response for the Saturday (March 14) trip and the availability of the railcars and locomotives led Amtrak and the resort to make a second ski excursion train run that Sunday (March 15),” Mark Murphy, the Chicago-based Amtrak general manager overseeing the trip, said in a statement.

Gary DeFrange, Winter Park Resort president and chief operating officer, said the interest in the trip shows the momentum for the train and the interest in its return.

“We share the public’s passion for this train as well as its hope for regular rail service in the future,” he said in a statement.

Tickets for up to 460 passengers to ride on March 15 are available from Amtrak.com/WinterParkExpress or by calling the resort at 888-923-7275.
